The Math.tanh() static method returns the hyperbolic tangent of a number. That is,
πΌπππ.ππππ(π‘)=tanh(x)=sinh(x)cosh(x)=exβeβxex+eβx=e2xβ1e2x+1\mathtt{\operatorname{Math.tanh}(x)} = \tanh(x) = \frac{\sinh(x)}{\cosh(x)} = \frac{\mathrm{e}^x - \mathrm{e}^{-x}} --> {\mathrm{e}^x + \mathrm{e}^{-x}} --> = \frac{\mathrm{e}^{2x} - 1}{\mathrm{e}^{2x}+1}
Syntax
Math.tanh(x)
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()
Math.tanh(-Infinity); // -1
Math.tanh(-0); // -0
Math.tanh(0); // 0
Math.tanh(1); // 0.7615941559557649
Math.tanh(Infinity); // 1
