Re: Should I study computer science?

Computer science is totally worth a shot. Computer science is more than just programming but you should check out some of the more theoretical classes and see if you like them (you never know until you try, after all) and, if you don't like them, concentrate more on software development if that's po...

Re: How much are you paying for books this semester?

I'm only taking four classes this semester and I'm trading some of my old textbooks for one I need this semester and one book is really inexpensive so I spent about $160 this semester for textbooks. Not bad, in my opinion.

Consider also a function f on (0,1) that oscillates wildly as it approaches 0, so that for every integer n, f(1/n) = 0, but in between these spots, it spikes up increasingly and arbitrarily high.

From what I can see, you shouldn't have to use the fact that the interval is open, because all that is necessary is that it is bounded. Without using delta-epsilon, my best thought is contraposition. Show that a function that is unbounded on (a.b) cannot be uniformly continuous by demonstrating two...
