      3 # Function tanh
      4 
      5 Calculate the hyperbolic tangent of a value,
      6 defined as `tanh(x) = (exp(2 * x) - 1) / (exp(2 * x) + 1)`.
      7 
      8 For matrices, the function is evaluated element wise.

     37 
     38 ```js
     39 // tanh(x) = sinh(x) / cosh(x) = 1 / coth(x)
     40 math.tanh(0.5)                   // returns 0.46211715726000974
     41 math.sinh(0.5) / math.cosh(0.5)  // returns 0.46211715726000974
     42 1 / math.coth(0.5)               // returns 0.46211715726000974
