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 y=log(1+ theta), x= sin^(-1) theta , then (dy)/(dx) =

If y=log(1+ theta), x= sin^(-1) theta , then (dy)/(dx) =

If x = a (theta + sin theta), y = b (1+ cos theta), then (dy)/(dx)" at "theta = (pi)/(2) is:

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

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

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

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