  /**
   * Calculate the cotangent of a value. Defined as `cot(x) = 1 / tan(x)`.
   *
   * To avoid confusion with the matrix cotangent, this function does not
   * apply to matrices.
   *
   * Syntax:
   *
   *    math.cot(x)
   *
   * Examples:
   *
   *    math.cot(2)      // returns number -0.45765755436028577
   *    1 / math.tan(2)  // returns number -0.45765755436028577
   *
   * See also:
   *
   *    tan, sec, csc
   *
   * @param {number | Complex | Unit | Array | Matrix} x  Function input
   * @return {number | Complex | Array | Matrix} Cotangent of x
