Yes, $\cos^2 (x)$ usually means $\cos(x) \cdot \cos(x)$. Most other information already given here is also correct: $\cos^2 x$ is probably most common as shortest
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).
Cos2x is an important trigonometric function that is used to find the value of the cosine function for the compound angle 2x. We can express cos2x in terms of different trigonometric functions and each of its formulas is used to simplify complex trigonometric expressions and solve integration problems.
