21 cze 2024 · 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: cos 2x = cos² x – sin² x, cos 2x = 2 cos² x – 1, cos 2x = 1 – 2 sin² x, and cos 2x = (1 – tan² x) / (1 + tan² x).
