How to simplify trigonometric functions

WebDec 20, 2024 · To define the trigonometric functions, first consider the unit circle centered at the origin and a point P = (x, y) on the unit circle. Let θ be an angle with an initial side that lies along the positive x -axis and with a terminal side that is the line segment OP. An angle in this position is said to be in standard position (Figure 1.7.2 ). WebThe proof of the identity goes as follows: It is well known that sin 2 ( x) + cos 2 ( x) = 1. Replacing x with arccos ( x), we have: sin 2 ( arccos ( x)) + cos 2 ( arccos ( x)) = 1. Because cos and arccos are inverse functions, cos 2 ( arccos ( x)) = x 2. Therefore sin 2 ( arccos ( x)) = 1 − x 2, and. sin ( arccos ( x)) = 1 − x 2.
