# Courses Do I need differentials before partial differentials?

### Y.E.T.I.

I know its a ridiculous question, but I'm signing up for classes and I wanted to take differential equations and its currently filled up(for now, people drop all the time at my uni) but saw partial differential equations. I assume you need differential equations before partial differential equations, so I don't know if I should even sign up for that. If I can't take it I'm going to take linear algebra.

yeah, it would make more sense. You also need a grasp of calculus 3.

I've signed up for calc 3 and physics 2. They let us take calc 3 concurrently with differential equations, I was just trying to avoid unneeded filler classes to make it full time. Linear algebra isn't really required but I thought it looked interesting.

What does the course catalog say about prerequisites?

I need differential equations before partial differential equations, just looked it up. Looks like linear algebra is gonna be a choice to take.

ODE is a very easy class. Can be a GPA booster

Excuse my ignorance, but what does ODE stand for?

Ordinary Differential Equations. (as opposed to Partial Differential Equations, PDE)

Oh ok. Thanks!

I get tripped up by TLA's sometimes, too.

If it helps, I wish linear algebra had been a prerequisite for my first class in differential equations. Linear algebra shows up everywhere, and there are big chunks of methodology in differential equations that boil down to solving a system of linear equations or finding eigenvalues or eigenvectors.
