WEB Cos2x is a trigonometric function that is used to find the value of the cos function for angle 2x. Its formula are cos2x = 1 - 2sin^2x, cos2x = cos^2x - sin^2x. WEB Aug 7, 2013 · Using trigonometric identities. Trigonometric identities like sin²θ+cos²θ=1 can be used to rewrite expressions in a different, more convenient way. For example, (1-sin²θ) (cos²θ) can be rewritten as (cos²θ) (cos²θ), and then as cos⁴θ. Created by Sal Khan.
