Katherine Wu. the . absolute value. of a number is its distance from 0 on a number line. distance is nonnegative so the absolute value of a number is always positive. symbol |x| is used to represent the absolute number of a number x. Differential Equations. In this class we will focus on solving ordinary differential equations that represent the physical processes we are interested in studying. With perhaps a few exceptions the most complicated differential equation we will look at will be second order, which means it will look something like.
