   * Calculate the hyperbolic cosecant of a value,
   * defined as `csch(x) = 1 / sinh(x)`.
   *
   * 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
   *
   * See also:
   *
   *    sinh, sech, coth
   *
   * @param {number | BigNumber | Complex} x  Function input
   * @return {number | BigNumber | Complex} Hyperbolic cosecant of x
