**Unit on Trig Ratios and Solving problems involving Right**

The inverse of the sine is the cosecant, the inverse of the cosine is the secant, and the inverse of the tangent is the cotangent. The abbreviations for these functions are, sin, cos, tan, csc, sec and cot, respectively.. What is underneath this idea is that for any (every!) right triangle, there is a fundamental relationship or ratio between the lengths of the sides for all triangles with the how to work out standerd deviation Trigonometric functions of inverse trigonometric functions are tabulated below. A quick way to derive them is by considering the geometry of a right-angled triangle, with one side of length 1, and another side of length x (any real number between 0 and 1), then applying the Pythagorean theorem and definitions of the trigonometric ratios.

**Inverse Trigonometric Functions Worksheets Trig Ratios**

The easiest way to work with inverse trig functions is to have a chart handy with the exact values of the functions. When you work with trigonometry a lot, you soon have the basic angles and their function values memorized. how to write a great inspirational speech Inverse trigonometric functions Now let us talk about inverse trigonometric relations. They are sometimes denoted with a -1 in the superscript of the trigonometric ratios and sometimes also denoted using arc as a prefix, for example, sin -1 , cos -1 , arctan etc.

## How To Use Inverse Trigonometric Ratios

“To find the angle measure for a given trigonometric ratio, start with the column for the selected ratio anywhere in the tables, and then move forward or backward, depending on the value of the ratio you are using. For example, to find the angle measure for the tangent = 0.80978, open the table to the tangent column and find any value. Move up or down the table in the tangent column to 0
