If x=r cos theta,y=r sin theta, show that

If x= r cos theta, y = r sin theta , then (del r)/(del x) =_________

If x = r cos theta, y = r sin theta, Find (del (x, y)) / (del (r, theta)), (del (r, theta)) / (del (x, y))

If x = r cos theta, y = r sin theta then prove that (del (x, y)) / (del (r, theta)) xx (del (r, theta)) / (del (x, y)) = 1

If x=r cos theta, y=r sin theta Prove that x^(2)+y^(2)=r^(2)

If x = r cos theta and y =r sin theta , then proof x^2 + y^2 = r^2

If w(x,y) =x^(y), x gt 0 , then (del w)/(del x) is equal to

Find dy/dx : x = r cos theta, y = r sin theta
