Webb9 maj 2016 · Explanation: Let's draw a right triangle with an angle of a = cos−1(x). As we know cos(a) = x = x 1 we can label the adjacent leg as x and the hypotenuse as 1. The Pythagorean theorem then allows us to solve for the second leg as √1 −x2. With this, we can now find sin(cos−1(x)) as the quotient of the opposite leg and the hypotenuse. sin ...

Subtracting cos 2 x from both sides, we get sin 2 x = 1 - cos 2 x. Thus, one of the sin squared x formulas is, sin2 x = 1− cos2x sin 2 x = 1 − cos 2 x. Using one of the double angle formulas of cosine function, we have cos 2x = 1 - 2 sin 2 x. dickens mutual friend crossword
