     18    * Calculate the tangent of a value. `tan(x)` is equal to `sin(x) / cos(x)`.
     19    *
     20    * For matrices, the function is evaluated element wise.
     21    *
     22    * Syntax:
     23    *
     24    *    math.tan(x)
     25    *
     26    * Examples:
     27    *
     28    *    math.tan(0.5)                    // returns number 0.5463024898437905
     29    *    math.sin(0.5) / math.cos(0.5)    // returns number 0.5463024898437905
     30    *    math.tan(math.pi / 4)            // returns number 1
     31    *    math.tan(math.unit(45, 'deg'))   // returns number 1
     32    *
     33    * See also:

     38    * @return {number | BigNumber | Complex | Array | Matrix} Tangent of x
