I have tried to solve these two integrals, but I get the wrong answer.
The first one is 4/x^2 - 4 (upper limit is 1, lower limit 0).
The correct answer is -ln2, but I get 2arctan(x/2) + c.
The next one is ln^2 x/2x (upper limit e^2, lower limit 1).
I am not sure what the correct answer is, but either
a) 4/3 b) 1/4 c) 3/5 d) 7/6 e) 4/9
I would appreciate your help,
