Webb12 sep. 2024 · cos (x)sin (x) + sin (x)cos (x) = sin (2x) But since we multiplied by 2 early on to get to that, we need to divide by two to make the equality, so cos (x)sin (x) = sin (2x) 2 Which is the reciprocal of sine x and cos x? These are trigonometric ratios. Sine x = sin x = Opposite side/hypotenuse. Cosine x = cos x = Adjacent side/hypotenuse. WebbConsidering the principal values of the inverse trigonometric functions, the sum of all the solutions of the equation cos –1 (x) – 2sin –1 (x) = cos –1 (2x) is equal to 0. Explanation: We are given that cos –1 x – 2 sin –1 x = cos –1 2x π ⇒ cos - 1 x - 2 ( π 2 - cos - 1 x) = cos - 1 2 x ⇒ cos –1 x – π + 2cos –1 x = cos –1 2x
