The TANH function calculates the hyperbolic tangent of a number. The function takes a single argument: any positive or negative integer or a decimal number. It belongs to the class of Math and Trig functions in Excel.

Hyperbolic functions such as the TANH function in Excel are used to calculate angles and distances in hyperbolic geometry. Let us look at an example where we must find the TANH value for some numbers. Apply the formula =TANH(A2) in cell B2. Press Enter and drag the Excel Fill handle till B4 to get the TANH values of the three numbers 0, -1, and 0.5. Thus, the function returns the hyperbolic tangent of the numbers, both positive and negative. It lies between the values of -1 and 1.
