You will be required to work with: all of diff eq, linear algebra(vector spaces, orthogonality conditions),Implicit function theorem, fourier series/transforms, laplace transforms....Basically all you have learned in math so far.

How about asking him? Do you seriously expect an answer to this question on this forum?he said the class average was 57% with many fails then how did he ace it?

Besides, the class average being 57% doesn't mean everything; maybe most of them just didn't work hard, or aren't too bright, or...

While I'm no expert on partial differential equations the only advice I can offer is the following:

* Be curious but to an extent.

What I mean by to an extent is that if you're too curious you will get sidetracked with your own curiosity and lose focus of the course but if you have no curiosity you will probably (I don't mean absolutely in this case) not understand it because math takes time to think about (even if only briefly it still is a thought).

* Ask questions if you are unsure

Like posters before me have said, don't be afraid to ask questions. If your ego gets in the way then get rid of it because we all need help at some point or another.

From what I do know about PDE's, most of the concepts of PDE's revolve highly around that of waves. So remember that understanding wave mechanics, picturing wave phenomena and thinking about certain transforms that deal with these related phenomena is important. You could almost say that PDE's are simply all about waves and nothing else in a sense.

When dealing with waves an important concept is that of orthogonality which is used to define the relationships in fourier transforms. But remember its all waves. Sums of waves, any decomposition of waves you can think of and that will help you become more adept with the subject.

Anyway I hope that advice serves you.

PDEs are totally intuitive man, I don't think the class even tried.

My sentiments exactly. He's your best friend, so what's wrong with asking him? Afraid you'll have to divulge in return your secret for acing a QM class?How about asking him? Do you seriously expect an answer to this question on this forum?
