Trig Cheat Sheet

The PDF file has four pages to print on both sides of the same sheet with the basic relationships of trigonometry. Use the password to open the PDF [PDF Document] file. Once the sheet is printed on both sides, it should be folded in half, so you will have a small booklet or book. The PDF file has two pages to print on both sides of a single sheet.

This leaflet will help you solve trig problems and make trigonometry homework easier.

In mathematics, the trigonometric functions are functions of an angle, important when studying triangles and modeling periodic phenomena. They 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.

The trigonometric functions are of great importance in Physics, Astronomy, Cartography, Boating, Telecommunications, the representation of periodic phenomena, and many other applications.

A trigonometric identity is an equality between expressions that contain trigonometric functions and is valid for all the values of the angle in which the functions are defined.
