Exact First-Order Differential Equations
We've looked at a few simple examples of first-order differential equations and how to solve them. Now let's take a look at exact first-order differential equations.
Professor Dave Explains
Classification of Differential Equations
Now that we know what differential equations are, we have to learn how to classify them. We have to know whether a DE is ordinary or partial, linear or nonlinear, homogenous or nonhomogenous, autonomous or nonautonomous. We have to be...

Homogeneous Differential Equations and Bernoulli Differential Equations
We have covered three classes of first-order differential equations, those being separable, linear, and exact. There are just two more to go over, those being homogenous and Bernoulli differential equations. What are these, how do we...
Professor Dave Explains
Separable First-Order Differential Equations
Now that we know how to classify differential equations, we have to learn how to solve them. Let's start with the easiest ones to solve, separable first-order differential equations. This will involve some simple algebra and then basic...
Professor Dave Explains
Linear First-Order Differential Equations
We just got our feet wet with separable differential equations, so now let's look at something slightly trickier. Solving linear first-order differential equations will require a little bit more effort, involving something called an...
