Cos(x^2)

Definition

The cosine function, denoted as cos(x), is a trigonometric function that gives the ratio of the adjacent side of a right triangle to its hypotenuse. In this case, we have cos(x^2), which means we are taking the cosine of x squared.

Trigonometric Function:

Trigonometric functions relate angles and lengths in triangles. Cosine is one of these functions.

Composite Function:

A composite function combines two or more functions together. In this case, we have a composition where x is squared before taking its cosine.

Periodic Function: A periodic function repeats its values after a certain interval. The cosine function has a period of 2π, meaning it repeats every 2π units on the x-axis.
