It totally depends on the person. For me: it's combinatorics / graph theory.

they are all hard. calculus is the hardest. if it isn't hard you are being cheated.

Most people I know would probably say calc 3 integrals, especially surface integrals, for some reason. But I don't think they're that bad, they're almost algorithmic to solve if you know a couple tricks.

I think algebraic topology is the hardest...so abstract.

Nah - at the time - complex function analysis.

Why the heck would anyone do that by hand? That's not mathematics, that's a computational problem. :grumpy:

lol, you can tell that to my prof :)

honestly, I think I learned a lot in that class. The tests weren't...umm...yeah, but the lectures were great. It was advanced applied linear algebra and he covered everything from intro to vector spaces, some hilbert space+infinite dimensional vector spaces, fourier series, complex linear algebra, jordan canonical form, finite-field linear algebra, boolean, gray, and error correcting codes, and elementary operators+quantum theory(spin and stern-gerlach)

couldn't really get more comprehensive than that :)

P.S. All you engineers please don't take this as an insult, I think my prof's comment was to illustrate that this course has very little pragmatic application, not that all engineers are failed math majors.

It's ok, I could easily say thermodynamics is the class that turns engineers into math majors. :tongue2:

I'm lucky that I minored in math (linear algebra) because it's very useful for quantum chemistry.

Sometimes I feel like I'm a math major (as I look at my field and wave electromagnetics book)

I vote for topology too. I think calc is easy. Very concrete. Linear Algrebra is easy too. Topology takes the cake. It is STRANGE!!!! Maybe abstract algebra. That is odd too.

So not only am I being cheated, but I also suck at the cheated version?

I found Diff EQ's to be painful (compared to Multivariable calc and linear algebra), since I couldn't visualize it. Sequences and series were pretty bad too, though, although I think that had more to do with me being asleep during class than anything else.

In fact, most of the hard math I've taken, I haven't had an interest in, because I haven't had to use it in physics yet. It's all just been "here, learn this" without a "ok, now we're going to use it".

Until this quarter... :(
