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'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.

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.

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

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 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.

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

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

a little ot, but if you have the time, check out discrete math... that starts knocking on some good will hunting sh1t

Physics and certain finance majors too

Took it last semester, after not having taken math for 3 years. It wasn't so bad. Brush up on integration by parts and partial fractions. Otherwise it's pretty straightforward as long as you put the time into understanding the concepts.

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

Laplace transforms will haunt my dreams forever. Know your linear algebra and calc 2 well and you wont have any issues. Very heavy on the integration.
