Feng shui and the Chinese zodiac both have roots in the I Ching, the ancient Chinese text that helps people determine lucky dates, among other predictions. Each year, Ng analyzes how the Chinese zodiac will affect everything from the global political climate to what the world's health will look like in the coming months.
The degree of a polynomial function is the highest exponent to which the dependent variable is raised. For example, f(x) = 4x 5 â x 2 + 5 is a fifth-degree polynomial, because its highest exponent is 5.
Memorize this: the degree of a polynomial is the largest degree of any one term in the polynomial. While we usually write polynomials with the largest degree term first, it's a good idea to look at the degrees of all the terms, in case some impish degree sprite came along and mixed them up to make our lives miserable.
