### TANH(number)

Returns the hyperbolic tangent of a number.

 number The number which you want the hyperbolic tangent of.

#### Remarks

 * The inverse of this function is the ATANH function.* The "number" is the angle in radians.* If "number" is not numeric, then #VALUE! is returned.* If your argument is in degrees, multiply it by PI/180 to convert it to radians.* If you want the result to be in degrees, multiply the result by 180/PI.* You can use the ATANH function to return the inverse hyperbolic tangent.* You can use the COTH function to return the reciprocal hyperbolic tangent (1/TANH).* You can use the SINH function to return the hyperbolic sine.* You can use the COSH function to return the hyperbolic cosine.* You can use the DEGREES function to convert from radians to degrees.* For a working example refer to the Quant > Hyperbolic Functions page.* For the Microsoft documentation refer to support.office.com
