+   * Calculate the hyperbolic cosecant of a value,

+   *
+   * To avoid confusion with the matrix hyperbolic cosecant, this function
+   * does not apply to matrices.
+   *
+   * Syntax:
+   *
+   *    math.csch(x)
+   *
+   * Examples:
+   *
+   *    // csch(x) = 1/ sinh(x)
+   *    math.csch(0.5)       // returns 1.9190347513349437
+   *    1 / math.sinh(0.5)   // returns 1.9190347513349437
