   * Calculate the hyperbolic cosine of a value,
   * defined as `cosh(x) = 1/2 * (exp(x) + exp(-x))`.
   *
   * To avoid confusion with the matrix hyperbolic cosine, this function does
   * not apply to matrices.
   *
   * Syntax:
   *
   *    math.cosh(x)
   *
   * Examples:
   *
   *    math.cosh(0.5)       // returns number 1.1276259652063807
   *
   * See also:
   *
   *    sinh, tanh
   *
   * @param {number | BigNumber | Complex} x  Function input
   * @return {number | BigNumber | Complex} Hyperbolic cosine of x
