# 9th Grade Math: Trigonometric Functions

In mathematics, the trigonometric functions are functions of an angle. They are important in the study of triangles and modeling periodic phenomena, among many other applications. Trigonometric functions are commonly defined as ratios of two sides of a right triangle containing the angle, and can equivalently be defined as the lengths of various line segments from a unit circle.

Many 9th grade math students find trigonometric functions difficult. They feel overwhelmed with trigonometric functions homework, tests and projects.
