The total curvature of the surface i.e., [tex]$\int_S K d \sigma$[/tex] of the surface given by [tex]$\frac{x^2}{9}+\frac{y^2}{25}+\frac{z^2}{4}=1$[/tex] , is [tex]$2\pi$[/tex].
To compute the total curvature of a surface S, given by the equation [tex]$\frac{x^2}{a^2}+\frac{y^2}{b^2}+\frac{z^2}{c^2}=1$[/tex], we can use the Gauss-Bonnet theorem.
The Gauss-Bonnet theorem relates the total curvature of a surface to its Euler characteristic and the Gaussian curvature at each point.
The Euler characteristic of a surface can be calculated using the formula [tex]$\chi = V - E + F$[/tex], where V is the number of vertices, E is the number of edges, and F is the number of faces.
In the case of an ellipsoid, the Euler characteristic is [tex]$\chi = 2$[/tex], since it has two sides.
The Gaussian curvature of a surface S given by the equation [tex]$\frac{x^2}{a^2}+\frac{y^2}{b^2}+\frac{z^2}{c^2}=1$[/tex] is constant and equal to [tex]$K = \frac{-1}{a^2b^2}$[/tex].
Using the Gauss-Bonnet theorem, the total curvature can be calculated as follows:
[tex]$\int_S K d\sigma = \chi \cdot 2\pi - \sum_{i=1}^{n} \theta_i$[/tex]
where [tex]$\theta_i$[/tex] represents the exterior angles at each vertex of the surface.
Since the ellipsoid has no vertices or edges, the sum of exterior angles [tex]$\sum_{i=1}^{n} \theta_i$[/tex] is zero.
Therefore, the total curvature simplifies to:
[tex]$\int_S K d\sigma = \chi \cdot 2\pi = 2\pi$[/tex]
Thus, the total curvature of the surface given by [tex]$\frac{x^2}{9}+\frac{y^2}{25}+\frac{z^2}{4}=1$[/tex] is [tex]$2\pi$[/tex].

Consider the parametric curve given by the equations x(t) = t² + 23t+ 47 y(t) = t² + 23t + 44 Determine the length of the portion of the curve from t = 0 tot = 7. (1 point) Suppose a curve is traced by the parametric equations x = 4(sin(t) + cos(t)) y = 28 – 12 cos² (t) — 24 sin(t) as t runs from 0 to π. At what point (x, y) on this curve is the tangent line horizontal? x= y =
The length of the portion of the curve from t = 0 to t = 7 is approximately 52.37 units.
To find the length of the portion of the curve, we can use the formula for the arc length of a parametric curve:
L = ∫[a,b] √((dx/dt)² + (dy/dt)²) dt,
where L represents the length, a and b are the parameter values corresponding to the desired portion of the curve, and dx/dt and dy/dt are the derivatives of x and y with respect to t, respectively.
In this case, we have the parametric equations x(t) = t² + 23t + 47 and y(t) = t² + 23t + 44, and we want to find the length of the curve from t = 0 to t = 7.
Differentiating x(t) and y(t) with respect to t, we get:
dx/dt = 2t + 23,
dy/dt = 2t + 23.
Substituting these derivatives into the arc length formula, we have:
L = ∫[0,7] √((2t + 23)² + (2t + 23)²) dt.
Simplifying the integrand, we have:
L = ∫[0,7] √((2t + 23)² + (2t + 23)²) dt
= ∫[0,7] √(4(t + 11.5)²) dt
= 2 ∫[0,7] |t + 11.5| dt.
Evaluating the integral, we get:
L = 2 ∫[0,7] (t + 11.5) dt
= 2 [(t²/2 + 11.5t) |[0,7]
= 2 [(7²/2 + 11.5 * 7) - (0²/2 + 11.5 * 0)]
= 52.37.
Therefore, the length of the portion of the curve from t = 0 to t = 7 is approximately 52.37 units.
The tangent line is horizontal at the point (4, 28) on the curve.
To find the point on the curve where the tangent line is horizontal, we need to find the values of t that make dy/dt equal to 0.
The given parametric equations are x = 4(sin(t) + cos(t)) and y = 28 – 12cos²(t) – 24sin(t), where t runs from 0 to π.
Taking the derivative of y with respect to t, we have:
dy/dt = 24sin(t) - 24cos(t)sin(t).
To find when dy/dt is equal to 0, we set the expression equal to 0 and solve for t:
24sin(t) - 24cos(t)sin(t) = 0.
Factoring out 24sin(t), we have:
24sin(t)(1 - cos(t)) = 0.
This equation is satisfied when either sin(t) = 0 or 1 - cos(t) = 0.
For sin(t) = 0, we have t = 0, π, 2π, 3π, and so on.
For 1 - cos(t) = 0, we have cos(t) = 1, which occurs at t = 0, 2π, 4π, and so on.
Since we are given that t runs from 0 to π, we can conclude that the only relevant value of t is t = 0.
Substituting t = 0 into the parametric equations, we get:
x = 4(sin(0) + cos(0)) = 4(0 + 1) = 4,
y = 28 - 12cos²(0) - 24sin(0) = 28 - 12(1) - 0 = 16.
Therefore, the point (x, y) on the curve where the tangent line is horizontal is (4, 28).

The circulation of F-4yi+2zj+2zk around the triangle obtained by using Stokes’ Theorem, tracing out the path (3,0,0) to (3,0,6), to (3,5,6) back to (3,0,0) is -14.
To find the circulation of F-4yi+2zj+ 2zk around the triangle obtained by tracing out the path (3,0,0) to (3, 0, 6), to (3, 5, 6) back to (3,0,0), we can use Stokes’ Theorem 1.
Stokes’ Theorem states that the circulation of a vector field F around a closed curve C is equal to the surface integral of the curl of F over any surface S bounded by C 2. In this case, we can use the triangle as our surface S. The curl of F is given by:
curl(F) = (partial derivative of Q with respect to y - partial derivative of P with respect to z)i + (partial derivative of R with respect to z - partial derivative of Q with respect to x)j + (partial derivative of P with respect to x - partial derivative of R with respect to y)k
where P = 0, Q = -4y, and R = 2z.
Therefore, curl(F) = -4j + 2i
The circulation of F around the triangle is then equal to the surface integral of curl(F) over S: circulation = double integral over S of curl(F).dS
where dS is the surface element. Since S is a triangle in this case, we can use Green’s Theorem to evaluate this integral 3:
circulation = line integral over C of F.dr
where dr is the differential element along C. We can parameterize C as follows: r(t) = <3, 5t, 6t> for 0 <= t <= 1
Then, dr = <0, 5, 6>dt and F(r(t)) = <0,-20t,12>
Therefore, F(r(t)).dr = (-20t)(5dt) + (12)(6dt) = -100t dt + 72 dt = -28t dt
The circulation is then given by:
circulation = line integral over C of F.dr = integral from 0 to 1 of (-28t dt) = -14

Given F(x, y) = (sin(x-y), -sin(x-y)) M a. Is F(x, y) conservative? b. Find the potential function f(x, y) if it exists.
The vector field F(x, y) = (sin(x-y), -sin(x-y)) is not conservative. Therefore, it does not have a potential function.
To determine if the vector field F(x, y) = (sin(x-y), -sin(x-y)) is conservative, we need to check if it satisfies the condition of being a gradient field. This means that the field can be expressed as the gradient of a scalar function, known as the potential function.
To test for conservativeness, we calculate the partial derivatives of the vector field with respect to each variable:
∂F/∂x = (∂(sin(x-y))/∂x, ∂(-sin(x-y))/∂x) = (cos(x-y), -cos(x-y)),
∂F/∂y = (∂(sin(x-y))/∂y, ∂(-sin(x-y))/∂y) = (-cos(x-y), cos(x-y)).
If F(x, y) were conservative, these partial derivatives would be equal. However, in this case, we can observe that the two partial derivatives are not equal. Therefore, the vector field F(x, y) is not conservative.
Since the vector field is not conservative, it does not possess a potential function. A potential function, if it exists, would allow us to express the vector field as the gradient of that function. However, in this case, such a function cannot be found.

If a linear transformation T: R^5 -> R^8 has a rank of 3, then the nullity of T is 2.
The rank-nullity theorem states that for a linear transformation T: V -> W, the sum of the rank of T and the nullity of T is equal to the dimension of the domain V. In this case, T: R^5 -> R^8, and Rank(T) = 3.
Using the rank-nullity theorem, we can find the nullity of T. The dimension of the domain V is 5, so the sum of the rank and nullity must be 5. Since Rank(T) = 3, the nullity of T is 5 - 3 = 2. In summary, if a linear transformation T: R^5 -> R^8 has a rank of 3, then the nullity of T is 2.

The general solution is y(t) = c1e^(-2t) + c2e^(3t) + c3e^(2t), where c1, c2, and c3 are arbitrary constants. The general solution is y(t) = c1e^(-2t) + c2e^((-1 + i√3)t) + c3e^((-1 - i√3)t), where c1, c2, and c3 are arbitrary constants. The general solution is y(t) = c1e^(i/√10)t + c2e^(-i/√10)t, where c1 and c2 are arbitrary constants.
(a) To find the general solution to y''' - 5y'' + 6y' +12y = 0, we can assume a solution of the form y(t) = e^(rt), where r is a constant. By substituting this into the equation and solving the resulting characteristic equation r^3 - 5r^2 + 6r + 12 = 0, we find three distinct roots r1 = -2, r2 = 3, and r3 = 2. Therefore, the general solution is y(t) = c1e^(-2t) + c2e^(3t) + c3e^(2t), where c1, c2, and c3 are arbitrary constants.
(b) For y'"' + 5y'' + 4y' - 10y = 0, we use the same approach and assume a solution of the form y(t) = e^(rt). By solving the characteristic equation r^3 + 5r^2 + 4r - 10 = 0, we find one real root r = -2 and two complex conjugate roots r2 = -1 + i√3 and r3 = -1 - i√3. The general solution is y(t) = c1e^(-2t) + c2e^((-1 + i√3)t) + c3e^((-1 - i√3)t), where c1, c2, and c3 are arbitrary constants.
(c) Finally, for y + 10y'' + 9y = 0, we can rearrange the equation to get the characteristic equation 10r^2 + 1 = 0. Solving this quadratic equation, we find two complex conjugate roots r1 = i/√10 and r2 = -i/√10. The general solution is y(t) = c1e^(i/√10)t + c2e^(-i/√10)t, where c1 and c2 are arbitrary constants.
In summary, the general solutions to the given higher-order differential equations are: (a) y(t) = c1e^(-2t) + c2e^(3t) + c3e^(2t), (b) y(t) = c1e^(-2t) + c2e^((-1 + i√3)t) + c3e^((-1 - i√3)t), and (c) y(t) = c1e^(i/√10)t + c2e^(-i/√10)t, where c1, c2, and c3 are arbitrary constants.

To find the particular solution of the equation e^(2y) = y', we can use the initial condition y(0) = 3. Given this initial condition, we need to find the value of y that satisfies both the equation and the initial condition.
The particular solution is y = In(2e - 401.429). This means that the function y is equal to the natural logarithm of the quantity 2e - 401.429.
To find the particular solution, we start with the given equation e^(2y) = y'. Taking the natural logarithm of both sides, we get 2y = ln(y'). Now we differentiate both sides with respect to x to eliminate the derivative, giving us 2y' = (1/y')y''. Simplifying this equation, we have y' * y'' = 2.
Integrating both sides with respect to x, we obtain ∫y' * y'' dx = ∫2 dx. This simplifies to y' = 2x + C, where C is an arbitrary constant. Using the initial condition y(0) = 3, we can solve for C and find that C = -401.429. Substituting this value of C back into the equation, we get y' = 2x - 401.429. Finally, we integrate y' to find y and arrive at the particular solution y = In(2x - 401.429).

(b) Let's find the cylindrical coordinates of (-7, 7√3, 7).The cylindrical coordinates are (r, θ, z).We know thatx = rcos θy = rsin θz = z
Substitute the values in the above equation.
r = sqrt((-7)² + (7√3)²) = 14tan θ = y/x
= -√3So, θ = 5π/6z = 7
The cylindrical coordinates of (-7, 7√3, 7) are (14, 5π/6, 7).
Hence, the cylindrical coordinates of (4,4,4) and (-7, 7√3, 7) are (4√2, π/4, 4) and (14, 5π/6, 7) respectively.

Evaluate the integral. #2+x² a) -dx √√x b) f(x² +ex) dx sin 2x -dx 1+ cos²x
(a) Integrating 2 with respect to u yields 2u + C. Reverting the substitution, we obtain the final result of 2√x + C.(b) Therefore, the second integral is equivalent to ∫dx/sin²x = ∫csc²x dx.
a) For the integral ∫-dx √√x, we can simplify the expression to ∫dx √√x. To evaluate this integral, we can use the substitution u = √x. Therefore, du = (1/2) √(1/√x) dx, which simplifies to 2du = dx/√√x. Substituting these values into the integral, we have ∫2du. Integrating 2 with respect to u yields 2u + C. Reverting the substitution, we obtain the final result of 2√x + C.
b) For the integral ∫f(x² + ex) dx sin(2x) - ∫dx/(1 + cos²x), the first term involves a composite function and the second term can be simplified using a trigonometric identity. Let's focus on the first integral: ∫f(x² + ex) dx sin(2x). To evaluate this integral, we can use a u-substitution by letting u = x² + ex.
Then, du = (2x + e) dx, and rearranging gives dx = du/(2x + e). Substituting these values, the integral becomes ∫f(u) sin(2x) du/(2x + e). Similarly, we can simplify the second integral using the identity 1 + cos²x = sin²x. Therefore, the second integral is equivalent to ∫dx/sin²x = ∫csc²x dx. By integrating both terms and re-substituting the original variable, we obtain the final result of the evaluated integral.

The functions sinh x and cosh x are defined as ex-e-x sinhx= 2 Use the Maclaurin series of e* to show that x2n+1 (a) sinhx=) n=0 (2n+1)! 2n (b) cosh x = [ (2n)! n=0 cosh .x = ex + e-x 2
Maclaurin series of sinh(x) and cosh(x) are as follows:sinh(x) = sum from n = 0 to infinity of x^(2n + 1) / (2n + 1)!cosh(x) = sum from n = 0 to infinity of x^(2n) / (2n)!
We have to show that x^(2n + 1) / (2n + 1)! represents the Maclaurin series of sinh(x), while the series for cosh(x) is given as sum from n = 0 to infinity of x^(2n) / (2n)!.
Expression of Maclaurin series
The exponential function e^x can be represented as the infinite sum of the series as follows:
e^x = sum from n = 0 to infinity of (x^n / n!)
The proof for Maclaurin series of sinh(x) can be shown as follows:
sinh(x) = (e^x - e^(-x)) / 2
= [(sum from n = 0 to infinity of x^n / n!) - (sum from n = 0 to infinity of (-1)^n * x^n / n!)] / 2
sinh(x) = sum from n = 0 to infinity of [(2n + 1)! / (2^n * n! * (2n + 1))] * x^(2n + 1)
Therefore, x^(2n + 1) / (2n + 1)! represents the Maclaurin series of sinh(x).
For Maclaurin series of cosh(x), we can directly use the given formula: cosh(x) = sum from n = 0 to infinity of x^(2n) / (2n)!
cosh(x) = (e^x + e^(-x)) / 2
= [(sum from n = 0 to infinity of x^n / n!) + (sum from n = 0 to infinity of (-1)^n * x^n / n!)] / 2
cosh(x) = sum from n = 0 to infinity of [(2n)! / (2^n * n!)] * x^(2n)
Therefore, [(2n)! / (2^n * n!)] represents the Maclaurin series of cosh(x).
Hence, the required Maclaurin series of sinh(x) and cosh(x) are as follows:sinh(x) = sum from n = 0 to infinity of x^(2n + 1) / (2n + 1)!cosh(x) = sum from n = 0 to infinity of x^(2n) / (2n)

O Under this transformation, one of the boundary of R is the map of the line v = u. OdA = 3dudv (0,0)
The correct expression for the integral of (2y - x) over the region S in the uv-plane using the given transformation is: SSR(2y - x)dA = S²(v – u)dudv. So, none of the given options are correct.
To determine the correct answer from the given options, let's analyze the given information and make the necessary calculations.
First, let's calculate the Jacobian of the transformation using the given substitutions:
Jacobian (J) = ∂(x, y) / ∂(u, v)
To find the Jacobian, we need to compute the partial derivatives of x and y with respect to u and v:
∂x/∂u = ∂(2x - y)/∂u = 2
∂x/∂v = ∂(2x - y)/∂v = -1
∂y/∂u = ∂(x + y)/∂u = 1
∂y/∂v = ∂(x + y)/∂v = 1
J = |∂x/∂u ∂x/∂v| = |2 -1|
|∂y/∂u ∂y/∂v| |1 1|
Determinant of J = (2 × 1) - (-1 × 1) = 2 + 1 = 3
The determinant of the Jacobian is 3, not equal to 1. Therefore, the statement "The Jacobian is equal to 1" is not correct.
Now let's examine the statement "Under this transformation, one of the boundaries of R is the map of the line v = u."
Since u = 2x - y and v = x + y, we can find the equation for the line v = u by substituting u into the equation for v:
v = 2x - y
So the line v = u is represented by v = 2x - y.
Comparing this with the equation v = x + y, we can see that they are not equivalent. Therefore, the statement "Under this transformation, one of the boundaries of R is the map of the line v = u" is not correct.
From the given options, the correct answer is:
SSR(2y - x)dA = S²(v – u)dudv
This is the correct expression for the integral of (2y - x) over the region S in the uv-plane using the given transformation.
Please note that the other options are not correct based on the analysis provided.

The solutions to the equation 2x² + 1 - 9 = 0, in the form x = N ± √D/M, are found by solving the equation and determining the values of N, D, and M. The value of N is -1, D is 19, and M is 2.
To solve the given equation 2x² + 1 - 9 = 0, we first combine like terms to obtain 2x² - 8 = 0. Next, we isolate the variable by subtracting 8 from both sides, resulting in 2x² = 8. Dividing both sides by 2, we get x² = 4. Taking the square root of both sides, we have x = ±√4. Simplifying, we find x = ±2.
Now we can express the solutions in the desired form x = N ± √D/M. Comparing with the solutions obtained, we have N = -1, D = 4, and M = 2. The value of N is obtained by taking the opposite sign of the constant term in the equation, which in this case is -1.

A Company produces three types of robots named A-bot, B-bot and C-bot. One unit of A- bot requires 7, 4 and 3 pieces of component X, Y and Z respectively, while one unit of B- bot requires 4, 7 and 3 pieces of components X, Y and Z respectively, and one unit of C- bot requires 3, 4 and 7 pieces of components X, Y and Z respectively. The company purchases the components X, Y and Z from its supplier at a unit cost of $4, $5 and $3 respectively. The production cost is 20% of the total component cost required to make the robots. To sell the robots, the company incurs a marketing cost of $3, $6 and $5 for each unit of A-bot, B-bot and C-bot respectively. On top of that, it also incurs a transportation cost of $7, $8 and $9 for each unit of A-bot, B-bot and C-bot respectively. One day, the company receives an order for 100 pieces of A-bot, 150 pieces of B-bot and 200 pieces of C-bot with a selling price of $70, $75 and $80 for each unit of A-bot, B-bot and C-bot respectively.

(d) Formulate a 1x2 matrix to represent the total marketing cost and total transportation cost. (e) Do you think the company should proceed with this order? Explain your answer.
The quantity of components X, Y, and Z required for the order can be represented by the matrix [100, 150, 200]. The total cost of the components is $1900. The company should proceed with the order as it would result in a profit of $41,706.
In this scenario, a company produces three types of robots (A-bot, B-bot, and C-bot) and receives an order for 100 A-bots, 150 B-bots, and 200 C-bots. The company incurs costs for components, production, marketing, and transportation. To analyze the situation, we need to formulate matrices for the quantity of components, total component cost, total production cost, and total marketing and transportation cost. Finally, we'll evaluate whether the company should proceed with the order.
(a) To represent the quantity of components X, Y, and Z required for the order, we can create a 1x3 matrix:
[tex]\[ \begin{bmatrix}100 & 150 & 200\end{bmatrix}\][/tex]
(b) To find the total cost of the three components, we can formulate a 3x1 matrix for the unit cost of each component:
[tex]\[ \begin{bmatrix}4 \\ 5 \\ 3\end{bmatrix}\][/tex]
By multiplying the quantity matrix from (a) with the unit cost matrix, we get:
[tex]\[ \begin{bmatrix}4 & 5 & 3\end{bmatrix} \cdot \begin{bmatrix}100 \\ 150 \\ 200\end{bmatrix} = \begin{bmatrix}1900\end{bmatrix}\][/tex]
The total cost of the components is $1900.
(c) To find the total production cost, including the component cost, we need to calculate 20% of the total component cost. This can be done by multiplying the total cost by 0.2:
[tex]\[ \begin{bmatrix}0.2\end{bmatrix} \cdot \begin{bmatrix}1900\end{bmatrix} = \begin{bmatrix}380\end{bmatrix}\][/tex]
The total production cost, including the component cost, is $380.
(d) To represent the total marketing cost and total transportation cost, we can create a 1x2 matrix:
[tex]\[ \begin{bmatrix}3 & 6 & 5\end{bmatrix}\][/tex]
The total marketing and transportation cost is $3 for A-bot, $6 for B-bot, and $5 for C-bot.
(e) Whether the company should proceed with this order depends on the profitability. We can calculate the total revenue by multiplying the selling price of each type of robot with the respective quantity:
[tex]\[ \begin{bmatrix}70 & 75 & 80\end{bmatrix} \cdot \begin{bmatrix}100 \\ 150 \\ 200\end{bmatrix} = \begin{bmatrix}42500\end{bmatrix}\][/tex]
The total revenue from the order is $42,500. To determine profitability, we subtract the total cost (production cost + marketing and transportation cost) from the total revenue:
[tex]\[42500 - (380 + 3 + 6 + 5) = 41706\][/tex]
The company would make a profit of $41,706. Based on this analysis, it appears that the company should proceed with the order as it would result in a profit.

To determine the open intervals on which the function is increasing or decreasing, we need to analyze the sign of the derivative of the function.
For the function h(x) = 7√[tex]xe^(2x),[/tex]let's find the derivative:
h'(x) =[tex](7/2)e^(2x)[/tex]√x + 7√x [tex]* (1/2)e^(2x)[/tex]
Simplifying further:
h'(x) =[tex](7/2)e^(2x)[/tex]√x + (7/2[tex])e^(2x)[/tex]√x
h'(x) [tex]= (7/2)e^(2x)[/tex]√x(1 + 1)
h'(x) = [tex]7e^(2x)[/tex]√x
To determine the intervals of increase or decrease, we need to analyze the sign of h'(x) within different intervals.
For x < 0:
Since the function is not defined for x < 0, we exclude this interval.
For 0 < x < 2:
In this interval, h'(x) is positive (since [tex]e^(2x)[/tex]> 0 and √x > 0 for 0 < x < 2).
Therefore, the function h(x) is increasing on the interval (0, 2).
For x > 2:
In this interval, h'(x) is also positive (since [tex]e^(2x)[/tex]> 0 and √x > 0 for x > 2).
Therefore, the function h(x) is increasing on the interval (4, ∞).
In conclusion, the function h(x) = 7√[tex]e^(2x)[/tex] is increasing on the open intervals (0, 2) and (4, ∞).

If T : P² → P¹ is given by T(p(x)) = p'(x), then A. Tis both one-to-one and onto. B. T is one-to-one but not onto. C. T is onto but not one-to-one
The function T : P² → P¹, given by T(p(x)) = p'(x), is one-to-one but not onto. In two lines, the summary of the answer is: The function T is injective (one-to-one) but not surjective (onto).
To determine whether T is one-to-one, we need to show that different inputs map to different outputs. Let p₁(x) and p₂(x) be two polynomials in P² such that p₁(x) ≠ p₂(x). Since p₁(x) and p₂(x) are different polynomials, their derivatives will generally be different. Therefore, T(p₁(x)) = p₁'(x) ≠ p₂'(x) = T(p₂(x)), which implies that T is one-to-one.
However, T is not onto because not every polynomial in P¹ can be represented as the derivative of some polynomial in P². For example, constant polynomials have a derivative of zero, which means there is no polynomial in P² whose derivative is a constant polynomial. Therefore, there are elements in the codomain (P¹) that are not mapped to by any element in the domain (P²), indicating that T is not onto.
In conclusion, the function T is one-to-one (injective) but not onto (not surjective).

(a) 2x² - y = 0 is the equation in Cartesian form for the given surface.
(b) x = 1/2 * y is the equation in Cartesian form for the given surface.
(a) To convert the equation 2θ = 4 + 4θ² into Cartesian form, we can use the trigonometric identities to express θ in terms of x and y.
Let's start by rearranging the equation:
2θ - 4θ² = 4
Divide both sides by 2:
θ - 2θ² = 2
Now, we can use the trigonometric identities:
sin(θ) = y
cos(θ) = x
Substituting these identities into the equation, we have:
sin(θ) - 2sin²(θ) = 2
Using the double-angle identity for sine, we get:
sin(θ) - 2(1 - cos²(θ)) = 2
sin(θ) - 2 + 2cos²(θ) = 2
2cos²(θ) - sin(θ) = 0
Replacing sin(θ) with y and cos(θ) with x, we have:
2x² - y = 0
This is the equation in Cartesian form for the given surface.
(b) To convert the equation p = sin(θ)cos(θ) into Cartesian form, we can again use the trigonometric identities.
We have:
p = sin(θ)cos(θ)
Using the identity sin(2θ) = 2sin(θ)cos(θ), we can rewrite the equation as:
p = 1/2 * 2sin(θ)cos(θ)
p = 1/2 * sin(2θ)
Now, we replace sin(2θ) with y and p with x:
x = 1/2 * y

Show that y(x) = c1 sin(2x) + c2 cos(2x) solves the differential equation y'' + 4y = 0. Then find the values c1 and c2 if y(0) = 0 and y'(0) = 1.
The given function y(x) = c1 sin(2x) + c2 cos(2x) is a linear combination of sine and cosine functions with coefficients c1 and c2. We can verify whether this function satisfies the differential equation y'' + 4y = 0 by taking its second derivative and substituting it into the differential equation.
Taking the second derivative of y(x), we have:
y''(x) = (c1 sin(2x) + c2 cos(2x))'' = -4c1 sin(2x) - 4c2 cos(2x).
Substituting y''(x) and y(x) into the differential equation, we get:
(-4c1 sin(2x) - 4c2 cos(2x)) + 4(c1 sin(2x) + c2 cos(2x)) = 0.
Simplifying the equation, we have:
-4c1 sin(2x) - 4c2 cos(2x) + 4c1 sin(2x) + 4c2 cos(2x) = 0.
The terms with sin(2x) and cos(2x) cancel out, resulting in 0 = 0. This means that the given function y(x) = c1 sin(2x) + c2 cos(2x) satisfies the differential equation y'' + 4y = 0.
To find the values of c1 and c2 that satisfy the initial conditions y(0) = 0 and y'(0) = 1, we can substitute x = 0 into y(x) and its derivative y'(x).
Substituting x = 0, we have:
y(0) = c1 sin(2*0) + c2 cos(2*0) = 0.
This gives us c2 = 0 since the cosine of 0 is 1 and the sine of 0 is 0.
Now, taking the derivative of y(x) and substituting x = 0, we have:
y'(0) = 2c1 cos(2*0) - 2c2 sin(2*0) = 1.
This gives us 2c1 = 1, so c1 = 1/2.
Therefore, the values of c1 and c2 that satisfy the initial conditions are c1 = 1/2 and c2 = 0.

The equation of the tangent line to the parabola f(x) = x² + 2x at the point (1, 3) is y = 4x - 1. The slope of the tangent line of the curve h(x) = x² at the point (1, 1) is 2.
To find the equation of the tangent line to the parabola f(x) = x² + 2x at the point (1, 3), we need to find the slope of the tangent line and the y-intercept. The slope of the tangent line is equal to the derivative of the function at the given point. Taking the derivative of f(x), we get f'(x) = 2x + 2. Plugging in x = 1, we find that the slope is m = f'(1) = 4.
Using the point-slope form of a linear equation, y - y₁ = m(x - x₁), we substitute the values x₁ = 1, y₁ = 3, and m = 4 to get the equation of the tangent line as y = 4x - 1.
For the curve h(x) = x², the derivative h'(x) = 2x represents the slope of the tangent line at any point on the curve. Plugging in x = 1, we find that the slope is m = h'(1) = 2. Therefore, the slope of the tangent line of h(x) at the point (1, 1) is 2.

Use the extended Euclidean algorithm to find the greatest common divisor of the given numbers and express it as the following linear combination of the two numbers. 3,060s + 1,155t, where S = ________ t = ________
The greatest common divisor of 3060 and 1155 is 15. S = 13, t = -27
In this case, S = 13 and t = -27. To check, we can substitute these values in the expression for the linear combination and simplify as follows: 13 × 3060 - 27 × 1155 = 39,780 - 31,185 = 8,595
Since 15 divides both 3060 and 1155, it must also divide any linear combination of these numbers.
Therefore, 8,595 is also divisible by 15, which confirms that we have found the correct values of S and t.
Hence, the greatest common divisor of 3060 and 1155 can be expressed as 3,060s + 1,155t, where S = 13 and t = -27.
