     23    * Calculate the inverse cosecant of a value, defined as `acsc(x) = asin(1/x)`.
     24    *
     25    * For matrices, the function is evaluated element wise.
     26    *
     27    * Syntax:
     28    *
     29    *    math.acsc(x)
     30    *
     31    * Examples:
     32    *
     33    *    math.acsc(0.5)           // returns number 0.5235987755982989
     34    *    math.acsc(math.csc(1.5)) // returns number ~1.5
     35    *
     36    *    math.acsc(2)             // returns Complex 1.5707963267948966 -1.3169578969248166 i
