## First Order Differential EquationsEdit

The simplest types of differential equations to solve are the **first order equations**. These are equations where the highest derivative in the equation is the first. So, a first order equation is a function ; there are no occurrences of or higher derivatives.

There are two easily solved types of first order equations. These are equations with **separable variables** and **linear equations**. This chapter covers how to solve and graph any equation in one of these forms, or reducible to these forms. Other types of differential equations, such as **non-linear equations**, are not covered yet.
