     21    * Calculate the cosecant of a value, defined as `csc(x) = 1/sin(x)`.
     22    *
     23    * For matrices, the function is evaluated element wise.
     24    *
     25    * Syntax:
     26    *
     27    *    math.csc(x)
     28    *
     29    * Examples:
     30    *
     31    *    math.csc(2)      // returns number 1.099750170294617
     32    *    1 / math.sin(2)  // returns number 1.099750170294617
     33    *
     34    * See also:
     35    *
     36    *    sin, sec, cot
     37    *
     38    * @param {number | Complex | Unit | Array | Matrix} x  Function input
     39    * @return {number | Complex | Array | Matrix} Cosecant of x
