For functions involving angles (trigonometric functions, inverse trigonometric functions, etc.) we follow the convention that all angles are measured in radians. Thus, for instance, the angle of $90\,^\circ$ is measured as $\pi/2$.

Definition

This function is defined as the composite of the cosine function and the square function. Explicitly, it is the function:

$\! x \mapsto \cos(x^2)$
