Detailed explanation-2: -Therefore, the derivative of sin x cos x is cos 2 x .
Detailed explanation-3: -Formulas and identities of sin 2x, cos 2x, tan 2x, cot 2x, sec 2x and cosec 2x are known as double angle formulas because they have angle double of the angle present in their formulas. Sin 2x formula is 2sinxcosx.
Detailed explanation-4: -Using one of the trigonometric formulas, we can write sin x as, sin x = cos (/2-x).
