# NCERT Solutions for Class 12 Maths Chapter 2 Exercise 2.1 Inverse Trigonometric Functions

NCERT solutions for class 12 maths chapter 2 exercise 2.1 inverse trigonometric functions focus on giving students an in-depth understanding of the inverse notations and what they mean. Thus, an inverse trigonometric ratio such as sin^{–1}x should not be confused with (sin x)^{ –1}. (sin x)^{ –1} = 1/sinx which is entirely different from sin^{–1}x. The next topic that this exercise target is the domain and range of inverse trigonometric functions. Kids are also taught how to draw graphs of these functions. For example, the graph of sin^{–1} function can be obtained from the graph of the original function by interchanging x and y axes, i.e., if (a, b) is a point on the graph of the sine function, then (b, a) becomes the corresponding point on the graph of the inverse sine function. Another point to be noted is that the graph of an inverse function can be obtained from the corresponding graph of the original function as a mirror image (i.e., reflection) along the line y = x. The class 12 maths NCERT solutions chapter 2 exercise 2.1 is proficient in delivering such concepts clearly to students.

NCERT solutions class 12 maths chapter 2 exercise 2.1 inverse trigonometric functions has 14 sums. The first 12 are relatively easy and require kids to find the principal value of a given inverse trigonometric function. The remaining 4 are slightly more difficult as they ask students to find the value of a mathematical expression using the concepts outlined in this section.
