How To Find Cos X Given Cos2X. To arrive at the formulas of cos^2x, we will use various trigonometric formulas. Use inverse trigonometric functions to find the solutions, and check for extraneous solutions. Cos2x, also known as the double angle identity for cosine, is a trigonometric formula that expresses the cosine of a double angle (2x) using various trigonometric functions. It can be represented in multiple forms: Follow along using the transcript. The first formula that we will use is sin^2x + cos^2x = 1 (pythagorean identity). A basic trigonometric equation has the form sin. Find the value of cos 2x use the trig identity:
