## CBSE Class 12 Mathematics Chapter 2 Inverse Trigonometric Functions

• The domains and ranges (principal value branches) of inverse trigonometric functions are given in the following table:
 Functions Domain Range (Principal Value Branches) [-1, 1]  [-1, 1]  R- [-1, 1] – {0} R-[-1, 1]  R  R • should not be confused with . In fact And similarly for other trigonometric functions.
• The value of an inverse trigonometric functions which lies in its principal value branch is called the principal value of that inverse trigonometric functions.
• For suitable values of domain, we have
