If x=a cos theta, y=a sin theta , then the value of (dy)/(dx) is -

If sin30^(@)=cos theta then minimum value of theta is

If 7 cos theta+5 sin theta = 5 , then find the value of 5 cos theta-7 sin theta .

If 7 sin theta +24 cos theta =25 , then what is the value of (sin theta +cos theta) ?

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 :

x sin ^ (3) theta + y cos ^ (3) theta = sin theta cos theta and x sin theta = y cos theta Find the value of x ^ (2) + y ^ (2)

If x sin^(3)theta+y cos^(3)theta=sin theta cos theta and x sin theta=y cos theta Find the value of x^(2)+y^(2)

If x sin^3 theta+ y cos^3 theta = sin theta cos theta and x sin theta = y cos theta, Find the value of x^2 + y^2.
