About 75 wpm with Qwerty. Also WOW if you're typing at 110 with Qwerty. With lot of chatting and foruming with Dvorak, you could get up to 160 easily.
Fastest typist on the world was clocked at around 215 wpm on Dvorak I think.
I switched to the Dvorak layout about a year ago and my wpm is around 120 or so right now. You won't get that with Qwerty.

I solved a pretty routine first-order diff. eq. where you simply separate the variables.
xcos(x)(dy/dx) - sin(y) = 0
=> \int cot(y)dy = \int dx/x
Now, I thought that you would get an arbitrary constant, C, on both sides and they would cancel each other out, but that's wrong. My book...
1. y = 3^^{}log_{}_{}_2^{}(t) Find dy/dx ... I tried using logarithmic differentiation but that didn't work.
2. \int x^{2x}(1 + ln x)dx\ ... I set u = x^{2x} but my du didn't quite work out right.

I found this a few weeks ago and it's a definite gold-mine. It's a relatively new website and they get new submissions all the time so hopefully the sections that lack extensive material expand.
I've been using the calculus section which is pretty good.
I thought local extremum did not exist at the endpoints of a closed bounded interval, however my textbook claims this.
