key term - Cos(t^2)

Definition

The function cos(t^2) represents cosine evaluated at t^2. It is often used in calculus problems to demonstrate how integrals and derivatives work with more complex functions.

Trigonometric Function:

A trigonometric function relates angles to ratios of side lengths in right triangles. Common examples include sine, cosine, and tangent.

Composite Function:

A composite function is formed when one function is applied to another. In this case, we have cosine applied to t^2, resulting in cos(t^2).

Even Function: An even function is symmetric with respect to the y-axis. The cosine function is an example of an even function because cos(-x) = cos(x).
