Using the above formula, we will proceed to the second step. Step 2: Substitute the values of a and b in the formula. sin x sin 7x = (1/2) [cos (x - 7x) - cos (x + 7x)] ⇒ sin x sin 7x = (1/2) [cos (-6x) - … Visa mer Sina Sinb is an important formula in trigonometry that is used to simplify various problems in trigonometry.
