The trigonometric functions are of great importance in Physics, Astronomy, Cartography, Boating, Telecommunications, the representation of periodic phenomena, and many other applications.Ī 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. 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. In mathematics, the trigonometric functions are functions of an angle, important when studying triangles and modeling periodic phenomena. Sum and Difference of Inverse Trigonometric Functions.Trigonometric functions in terms of the Other Five.This leaflet will help you solve trig problems and make trigonometry homework easier. The PDF file has two pages to print on both sides of a single sheet. Once the sheet is printed on both sides, it should be folded in half, so you will have a small booklet or book.

2 Unit circle definition For this definition q is any angle. Cheat sheets on Graph Transformations ( Basic and Advanced) are also available on this website. Definition of the Trig Functions Right triangle definition For this definition we assume that p 0 < q < or 0 < q < 90. You also must have a strong grasp on graph transformations, which will help you to understand the relation between the graphs of trigonometric functions and inverse trionometric functions. A cheat sheet on Trigonometry is also available on this website. A study of these functions gives a good insight into the behaviour, domains and ranges of inverse functions in general.Ī good knowledge of the basic formulae of trigonometry is a must to understand and solve problems related to inverse trigonometry. This topic is a part of trigonometry and is an intersection of two major concepts – inverse of a function and trigonometry.

This cheat sheet covers the high school math concept – Inverse Trigonometric Functions.
