Deriving 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 Let us equate, X and Y, i.e.

cos ˇ 2 = sin ; cos(ˇ ) = cos : 6. tg ˇ 2 = ctg ; ctg ˇ 2 = tg : 7. sec ˇ 2 = cosec ; cosec ˇ 2 = sec : 8. sin 2 + cos = 1: 9.

We use the formula cos (A +B) = cos A cos B – sin A sin B, to obtain the formulæ of cos 2x. The formulas of cos (2x) as following: Cos (2x)= 2 (cosx)^2–1.
