If x = a{costheta + log tan((theta)/(2))} andy = a sin theta, then (dy)/(dx) is equal to

If x = a (cos x + log tan theta/2) and y = a sin theta then dy/dx is equal to

If x=a(cos theta+log tan((theta)/(2))) and y=a sin theta then find (dy)/(dx) at theta=(pi)/(3) and theta=(pi)/(4)

If x=acos^(3)theta and y=asin^(3)theta , then (dy)/(dx)=

If x=a(costheta+log"tan"(theta)/(2)) and y=asin theta , then find the value of (dy)/(dx) at theta=(pi)/(4) .

If x = a (cos theta + log tan(theta/2)) and y = a sin theta , find the value of (d^2y)/(dx^2) at theta = pi/4

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