How to Prepare Inverse Trigonometry for Class 12 Mathematics-NCERT

Updated: Sep 11, 2022

Inverse Trigonometry is an Integral Part of Class 12 Mathematics and is used extensively in Differential and Integral Calculus. But how will you prepare for it?

Very often, the entire sight of these formulas seem to put you off. But rest assured, that inverse trigonometry is very easy, once you learn how to go about it the right way. And that is precisely what this blog is going to teach you!

A function is invertible if it is bijective. You know that trigonometric functions are periodic and hence not bijective in general. But if we restrict their domains and codomains, they can become bijective in these intervals and hence their inverses exist.

Keeping this in mind, you will learn the domain and range of the basic trigonometric functions in this picture.
