If `x=3+2cos theta,y=5+2sin theta` than the locus of the point `(x,y)` is a circle with centre and radius

If x=2+3cos theta and y=1-3sin theta represent a circle then the centre and radius is

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

If x=3cos theta-2cos^(3)theta,y=3sin theta-2sin^(3)theta, then (dy)/(dx) is

x=3costheta-2cos^(3)theta, y = 3 sin theta- 2 sin^(3) theta

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

If sin x cosh y = cos theta, cos x sinh y = sin theta then sinh ^ (2) y =

If x sin^(3) theta + y cos^(3) theta = sin theta cos theta and x sin theta = y cos theta , then the value of x^(2) + y^(2) is :
