In this lesson, we will learn how to approximate trigonometric functions when the angle of the function is close to zero.

Students will be able to

approximate , , and when is close to zero radians,
use the small angle approximations of the trigonometric functions to approximate the values of trigonometric expressions,
calculate the percentage error when approximating a trigonometric function using the small angle approximations,
use the small angle approximations of the trigonometric functions to prove trigonometric proofs.
