1. INT {-1 to 1} ln(x+2)dx(adsbygoogle = window.adsbygoogle || []).push({});

u=x+2

du=dx

1/(x+2)

When I use FTC, I get -.6667, not what I get with a calculator.

2. INT {2 to 3} dx/x^2-x

ln|x^2 -x|

then FTC, and different answer from calc.

I'm sure these are connected somehow. I havn't touched these in a long time, so I am guessing I am forgetting some step...
