" The wifore fas "2sin theta cos theta=sin2 theta

cos theta+sin theta=cos2 theta+sin2 theta

sin2 theta=2sin theta cos theta

If sin2 theta = cos 3 theta then theta =

Prove that : (1+sin2 theta-cos 2theta)/(sin theta+cos theta)=2sin theta

If f(theta)=|(cos^(2) theta, cos theta sin theta, -sin theta),(cos theta sin theta, sin^(2) theta, cos theta),(sin theta, -cos theta, 0)| then f((pi)/12)=

If 2 - cos^(2) theta = 3 sin theta cos theta , sin theta ne cos theta then tan theta is

Prove that, (1 + sin 2 theta - cos 2 theta)/(sin theta + cos theta)= 2 sin theta

Prove that : (1-sin theta cos theta)/ (cos theta (sec theta - cosec theta)) times (sin^2 theta - cos^2 theta)/(sin^3 theta + cos^3 theta) = sin theta
