   * Calculate the inverse cosecant of a value, defined as `acsc(x) = asin(1/x)`.
   *
   * For matrices, the function is evaluated element wise.
   *
   * Syntax:
   *
   *    math.acsc(x)
   *
   * Examples:
   *
   *    math.acsc(0.5)           // returns number 0.5235987755982989
   *    math.acsc(math.csc(1.5)) // returns number ~1.5
   *
   *    math.acsc(2)             // returns Complex 1.5707963267948966 -1.3169578969248166 i
