Differential Equations

What should I brush up on for this class? Smells like a lot of Cal2 and heavy integration. This is my last math class required, and I took Cal2 a year ago so I'm bit rusty on it..just want to see what others thought of the course.

it ramps up, so if you didn't pay someone to pass your calc finals, it'll come back to you.

I was decent at Calc2, got out with a B but its been a year since I've done some of the heavy integration. Just trying to get a feel for what to expect outta the course.

iirc, heavy integration is in multivariable calc. differential equations is a lot of derivatives f'(x) f''(x) f'''(x) etc

Yup. Calc III is a breeze, literally calc I integrations in 3D. I've been working diff eq problems off an on all summer to get ready and have done zero integration.

We really didn't do a lot of Multivarible integration in Calc3. It was mainly applications. That's why Cal2 is a prerequisite for DiffEQ, not Cal3.

Cal2 IS integral calculus so thats where you see most of it

I'm in the same boat, but I took calc III 5 years ago, so this should be fun.

edit: I'm still surprised you don't have to take linear algebra for EE

I have heard of these "differential equations" of which you speak.

5 years ago?! How long have you been an engineering student?

It's the Comp Sci guys that really use linear algebra.

LOTS of linear algebra in quantum mechanics, in fact it's all linear algebra

How would you rank QM as far as difficulty relative to other undergrad classes? The difference between a BA and a BS for me is QM II and Diff Eq II.

As far as difficulty is concerned, I think it's about the same as any other upper division undergrad class (just a bit counterintuitive at first), and I would definitely recommend taking it. At least to me it was very interesting. I only took one Diff Eq class, so I can't say how it would compare to the more advanced Diff Eq classes.

I was too. Most uni's roll Linear into Calc2 when they do Cross prodcut and other light algebra, but they don't make you take a stand alone Linear Algebra Class.


Compsi guys use it alot more but Southern Polytech doesn't have a standalone requirement for it if you transfer in. Most Uni's make you take a stand alone class if you are transferring in.

This happens for me a lot. When you really understand whats happening and you catch yourself in the middle of a sailboat race, or at the controls of a small airplane, its just impressive.

It's not bad at all, had it two semesters ago. Although, my professor was terrible and I taught myself. More derivatives than anything. LaPlace transformation is what stumped me the most. Watch YouTube videos on it as well, helped alot

i dont have any tips, but i just wanna say that this class came within an inch of ending my engineering career back in college. i think residual post-traumatic stress from this class is what finally pushed me to go to law school and leave all this behind

Meh, its my last math class for an EE. The great thing about engineering degrees is if you can survive the math, the rest isn't so bad.

I think Engineers and Math majors are the only ones required to take this nonsense
