If cos p`theta` + cos q`theta` = 0 and if p `ne` q, then `theta` is equal to (n is any integer )

cos p theta=cos q theta,p!=q, thetn

If a cos theta + b sin theta = p and asin theta - bcos theta = q , then the relation between a, b, p and q is____

Solve : cos p theta = sin q theta.

If a cos theta + b sin theta = p and a sin theta - b cos theta = q , then the relation between a,b,p and q is

If sin theta + cos theta =p and tan theta+ cot theta = q then q (p^(2) -1) =

If sin theta + cos theta = and sin^(3) theta + cos^(3)theta = q, then p(p^(2) - 3) =

P (cos theta , - cos theta ) , Q( sin theta , sin theta ) then PQ = ......
