static method returns the hyperbolic tangent of a number. That is,
Try it
Syntax

.
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
