If sin A + cos A = p and sec A + cosec A = q , then prove that : q(p^(2) - 1) = 2 p

If sin theta+cos theta=p and sec theta+cos ec theta=q show that q(p^(2)-1)=2p

If sin theta+cos theta=p and sec theta+csc theta=q show that q(p^(2)-1)=2p

If sin theta+ cos theta = p and sec theta + cosec theta = q ; show that q(p^2-1) = 2p

If cos theta + sin theta = p and sec theta + cosec theta = q , prove that q (p^(2) - 1) = 2p .

If sin theta + cos theta = p and sec theta + "cosec"theta = q , then prove that q(p^(2)-1) = 2p .

If x = a sec A cos B, y = b sec A sin B and z = c tan A, show that : (x^(2))/ (a^(2)) + (y^(2))/ (b^(2)) - (z^(2))/(c^(2)) = 1

If sin theta+cos theta=p and sec theta+cos ec theta=q find q(p^(2)-1)=
