Inverse Trigonometric Functions

Inverse Trigonometric Functions

• Trigonometric functions are not one-one and onto in their usual natural domain. Hence, they are not invertible.

They can be made one-one and onto (i.e., invertible) by restricting their domain. In this case, the

• Range of the inverse of trigonometric function is the proper subset of the domain of that trigonometric function.
• The branch of the inverse trigonometric function with the restricted range is called the Principal Value Branch.
• There are 6 inverse trigonometric functio...
