Hi, you guys are great help.
I'm reviewing for an exam I have in a few hours (it's costing me sleep, but I guess it's worth it), and I'm using a review "packet" which apparently has the same "format" of questions as on the actual test. (So in other words, there will be different values, but same set-up) Anyways, I've completed a few problems and I'm hoping if some of you can check 2, and show me how to do some others. Thanks.
I'm sorry if it seems like I'm overkilling it by including more than one question, but apparently I'm running out of questions I can ask.
Problems I've done, and need checked:
1) Integral of e^(1/x+1)/(x+1)^2 dx
For that, I got -e^(1/x+1)+c
2) Integral of 1/(x^2)(e^(2/x))dx
For that, I got -1/2(e^-2/x) + c
Questions I need full assistance with:
3) Evaluate Integral of e^x/(e^x + 1)^(1/2) dx
4.) Evaluate Definite Integral 1/x-1 dx; b(top):e+1 a(bottom):2
Thanks.
