Introduction

In this topic we prove some important properties of inverse trigonometric functions. These results are valid within the principal value branches of the corresponding inverse trigonometric functions and wherever they are defined. These properties can be used to solve numerous inverse trigonometric problems by making them easier.

Key Words / FlashCards
Key Words Definitions (pref. in our own words)
Range The range of a function refers to either the co-domain or the image of the function, depending upon usage. The co-domain is a set containing the function's output, whereas the image is only the part of the co-domain where the elements are outputs of the function.
Domain The domain of definition or simply the domain of a function is the set of "input" or argument values for which the function is defined.
Trigonometric Functions The trigonometric functions (also called circular functions) are functions of an angle. They are used to relate the angles of a triangle to the lengths of the sides of a triangle.
Inverse trigonometric Functions The inverse trigonometric functions (occasionally called cyclometric functions) are the inverse functions of the trigonometric functions with suitably restricted domains.

Real life uses :

Digital imaging is a real life application of trigonometry. Computer generation of complex imagery is made possible by the use of geometrical patterns that define the precise location and color of each of the infinite points on the image to be created. The image is made detailed and accurate by a technique referred to as triangulation. The edges of the triangles that form the image make a wire frame of the object to be created and contribute to a realistic picture.

Practical examples around us
Examples Explainations
Trigonometry can be used to measure the heights of mountains We measure mountains because this information is of great value for aircraft designing and navigation. Also those people with medical conditions that prevent them from traveling to very high altitudes need to know the altitudes they will be travelling at so as to be sure that it’s safe for travel.
