Hello!

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,

best wishes

Amine
