Function tanh
Calculate the hyperbolic tangent of a value,
defined as tanh(x) = (exp(2 * x) - 1) / (exp(2 * x) + 1).
For matrices, the function is evaluated element wise.
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
