/**
|
|
* Calculate the hyperbolic tangent of a value,
|
|
* defined as `tanh(x) = (exp(2 * x) - 1) / (exp(2 * x) + 1)`.
|
|
*
|
|
* To avoid confusion with matrix hyperbolic tangent, this function does
|
|
* not apply to matrices.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.tanh(x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* // tanh(x) = sinh(x) / cosh(x) = 1 / coth(x)
|
|
* math.tanh(0.5) // returns 0.46211715726000974
|
|
* math.sinh(0.5) / math.cosh(0.5) // returns 0.46211715726000974
|
|
* 1 / math.coth(0.5) // returns 0.46211715726000974
|
|
*
|
|
* See also:
|
|
*
|
|
* sinh, cosh, coth

|
*
|
|
* @param {number | BigNumber | Complex} x Function input
|
|
* @return {number | BigNumber | Complex} Hyperbolic tangent of x
