" 23.If "x=cos theta,y=sin theta" then "(dy)/(dx)

1. If x = at ^(2) , y = 2 at then (dy)/(dx) at t =1 is A 2 If x =cos theta, y = sin theta then (dy)/(dx) at theta = (pi)/(4) is B 3 If x =1 - cos theta, y = sin theta , then (dy )/(dx) at theta = (pi)/(6) is C 4 If x = log sin theta, y = tan theta then (dy)/(dx) at theta = (pi)/(4) is D. The ascending order of A,B,C,D is

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

x=a cos theta,y=b sin theta then find dy/dx

x=a cos theta,y=a sin theta Find dy/dx

If x=cos theta-cos2 theta,y=sin theta-sin2 theta then (dy)/(dx) is

If x=2cos theta -cos 2theta ,y=2sin theta -sin 2theta ,then (dy)/(dx) =

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)

If x=2 cos theta- cos 2 theta and y=2 sin theta - sin 2 theta, then (dy)/(dx) =
