If x=a sin theta,y=b tan theta, then

x = a cos theta, y = b sin theta .

If x = a cos theta and y = b sin theta , find (dy)/(dx)

If x = a cos theta and y = b sin theta , find (dy)/(dx)

x=b sin^(2)theta & y=a cos^(2)theta

If (x)/(a)cos theta+(y)/(b)sin theta=1 and (x)/(a)sin theta-(y)/(b)cos theta=-1, prove that (x^(2))/(a^(2))+(y^(2))/(b^(2))=2

If x =a cos theta , y =b sin theta then (dy)/(dx) =

If (x)/(a)cos theta+(y)/(b)sin theta=1 and (x)/(a)sin theta-(y)/(b)cos theta=1 Prove that :(x^(2))/(a^(2))+(y^(2))/(b^(2))=2

(x) / (a) cos theta + (y) / (b) sin theta = 1, (x) / (a) sin theta- (y) / (b) cos theta = 1 then (x ^ (2)) / (a ^ (2)) + (y ^ (2)) / (b ^ (2)) =

x=a cos theta+b sin theta and y=a sin theta-b cos theta show that y^(2)(d^(2)y)/(dx^(2))-x(dy)/(dx)+y=0
