Half angle of tan

WebThe half angle formula for sine function is sin a/2 = ±√ [ (1 – cos a) / 2] What is the half angle formula for cosine function? The half angle formula for cosine function is cos a/2 = ±√ [ (1 + cos a) / 2] What is the half angle formula for tangent function? The half angle formula for tangent function is tan a/2 = ±√ [1 – cos a] / [1 + cos a] This is a geometric way to prove the particular tangent half-angle formula that says tan 1 / 2 (a + b) = (sin a + sin b) / (cos a + cos b). The formulae sin 1 / 2 (a + b) and cos 1 / 2 (a + b) are the ratios of the actual distances to the length of the diagonal.
