WebDeriving Double Angle Formulae for Cos 2t. 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 = Cos2t – Sin2t. And this is how we get second double-angle formula ...
