Syntax
Parameters
x-
A number.
Return value
The hyperbolic tangent of x.
Description
Because tanh() is a static method of Math, you always use it as Math.tanh(), rather than as a method of a Math object you created (Math is not a constructor).
Examples
Using Math.tanh()
js
Math.tanh(-Infinity); // -1
Math.tanh(-0); // -0
Math.tanh(0); // 0
Math.tanh(1); // 0.7615941559557649
Math.tanh(Infinity); // 1
