  /**
   * Calculate the cosecant of a value, defined as `csc(x) = 1/sin(x)`.
   *
   * To avoid confusion with the matrix cosecant, this function does not
   * apply to matrices.
   *
   * Syntax:
   *
   *    math.csc(x)
   *
   * Examples:
   *
   *    math.csc(2)      // returns number 1.099750170294617
   *    1 / math.sin(2)  // returns number 1.099750170294617
   *
   * See also:
   *
   *    sin, sec, cot
   *
   * @param {number | BigNumber | Complex | Unit} x  Function input
   * @return {number | BigNumber | Complex} Cosecant of x
