     15    * Calculate the inverse cosecant of a value, defined as `acsc(x) = asin(1/x)`.
     16    *
     17    * For matrices, the function is evaluated element wise.
     18    *
     19    * Syntax:
     20    *
     21    *    math.acsc(x)
     22    *
     23    * Examples:
     24    *
     25    *    math.acsc(0.5)           // returns number 0.5235987755982989
     26    *    math.acsc(math.csc(1.5)) // returns number ~1.5
     27    *
     28    *    math.acsc(2)             // returns Complex 1.5707963267948966 -1.3169578969248166 i
