x+2y=sqrt(y)

Calculate div F and curl F for F = rn (xi + yj). (simplify the differentiation by using rx=x/r, ry=y/r) For which value(s) of n is div F=0? For which value(s) of n...

An engine part is a solid S in the shape of an Egyptian-type pyramid having height 2 and a square base with diagonal D of length 2. Inside the engine it rotates about D. Set up an iterated integral...

Having difficulty finding them I can only find one ??(??,??)=2??^5 ??^2+??^2 ??

A solid D is bounded below by a right circular cone whose generators have length a and make an angle π/6 with the central axis. It is bounded above by a portion of the sphere of radius a centered...

verify green's theorem in the normal form by calculating both sides and showing they are equal if F= x2i + xyj, and C is the square with opposite vertices at (0,0) and (1,1)

Let F= i + j. How would you place a directed line segment C of length one so that the value of ∫cF*dr would be a. a maximum b. a minimum c. zero d. what would the...

lim x approches 0, ((4x-1)3)/(sin(x/p)log(1/(x2/3))) = 12(In4)3

The graph is continuous [0,3]. It is decreasing on [0,2] and increasing [2,3], differentiable at each point in(0,3) except at 1 where there is a vertical tangent.

A. let f(x,y)= xexy, and C be the path y=1/x from (1,1) to (0,∞) 1. calculate F=∇f 2. Calculate the integral ∫cF*dr ...

I have an integral with ∫ (b=0, a=-1) and the inside function is (2t)/[(3+t2)3]dt. The directions tell me to "Evaluate the definite integral by making a u-substitution and integrating...

The answer of this question is (-∞,-5)U(-5,-3]U[3,5)U(5,∞). I don't know how the 5 and -5 come out.

Formula for what is 3.14 squared x plus 2 divided by a radius .505 y to the liner equation that point at x=y

I need help with this problem Suppose that y′=ky, y(0)=12, and y′(0)=13. What is y as a function of t ?

find the area of the ellipse (x+2y)2 + (3x+4y)2 =1

Determine a vector equation for the plane that is parallel to the xy -plane and passes through the point (4, 1, 3).

ive got 3 questions lim x approaches positive 1 (sq rt of x^2 - 1) / (arcsecx) lim x approaches 0 2arctan3x^2 / 7x^2 initial value prob dy/dx=1/(x^2+1)...

This is calculus 2 problem

This graph is defined at [1,3] but is not continuous at x=2.

I am having some points on sphere and I want to represent these points on 2D surface. It would be better or easy to understand if you can explain with some example.
