Thanks a ton!

I also figured out (eventually) the point where I was stuck:

(2x - x^3 - 1) / (x - 1)

Can't really factor from that, so I just multiplied everything by the conjucate of the denominator (x + 1) .. worked!

The concepts of calc are so easy, but it's the algebra I get stuck with... there's always an obvious way out when doing a complex problem, but it takes me FOREVER to find it..

[edit]
Nevermind, I'm all mixed up on that one. The conjugate worked only on the numerator, which gave -1, but jumped the gun without working the bottom, which still came out to 0, since I KNEW to expect -1.. so I got all "oh good, I finally found it.." when I didn't.

Working the derivative through AGAIN gave me -1, so I think I just really f'd something up in my algebra the first few times.
