Let’s start by considering the addition formula. Cos(A + B) = Cos A cos B – Sin A sin B. Let’s equate B to A, i.e A = B. And then, the first of these formulae becomes: Cos(t + t) = Cos t cos t – Sin t sin t. so that Cos 2t = Cos 2 t – Sin 2 t Dividing all elements of the diagram by cos α cos β provides yet another variant (shown) illustrating the angle sum formula for tangent. These identities have applications in, for example, in-phase and quadrature components .

3 . We can determine the half-angle formula for tan ( x 2 ) = 1 − cos x 1 + cos x tan ( x 2 ) = 1 − cos x 1 + cos x by dividing the formula for sin ( x 2 ) sin ( x 2 ) by cos ( x 2 ) . cos ( x 2 ) .
