NCERT Solutions for Class 12 Maths Chapter 2 Inverse Trigonometric Functions – Exercises

In Chapter 2 of NCERT Solutions for Class 12 Maths, students will deal with inverse trigonometric functions and their properties. Get handy with the domains and ranges (principal value branches) of inverse trigonometric functions by the solutions provided by BYJU’S. While solving problems on this topic, students should keep in mind that the value of an inverse trigonometric function, which lies in its principal value branch, is called the principal value of the given inverse trigonometric function. The topics explained in Chapter 2 of NCERT Solutions for Class 12 of Maths include:

2.1 Introduction

In the earlier classes, students have already learnt about functions and necessary conditions for the existence of the inverse function. Here, you will learn about the possibilities of defining an inverse trigonometric function.

2.2 Basic Concepts

In this exercise, students can gain knowledge of trigonometric functions such as sine, cosine, tangent, cot, cosec, and sec. Also, they can gain in-depth knowledge of the concept of an inverse trigonometric function, finding the principal value of the inverse trigonometric function, domain, and range of the inverse trigonometric function. Besides, graphs of inverse trigonometric functions are also discussed.
