Prove. csc theta - 2 sin theta = cos 2 theta over sin theta Prove the following identity. cot theta - tan theta = cos 2 theta / sin theta cos theta Prove the identity. cos (pi - theta) + sin (pi / 2 + theta) = 0 Prove that, sin theta + sin 2 th...
Now, using the trigonometry identity \[\sin \left( A+B \right)=\sin A\cos B+\cos A\sin B\], we get $\sin 5\theta =\sin 3\theta \cos 2\theta +\cos 3\theta \sin 2\theta ...\left( ii \right)$ Now, we can use trigonometric identities of $...
