The value of x is equal to the hyperbolic tangent of y. x = tanh y, Therefore, the value of y is equal to the inverse hyperbolic tangent of x. y = tanh − 1 x, So, the relation between them can be written in mathematics as follows. x = tanh y ⇔ y = tanh − 1 x, 01.

Let us look at some examples to understand the meaning of inverse. Example 1: The addition means to find the sum, and subtraction means taking away. So, subtraction is the opposite of addition.
