[Maxima] Newbie question

Dear all,

I've decided to switch to maxima.
So I will come here with obvious questions --
A first one:
-------------------------------------------------
(%i23) facts();
(%o23) [eps > 0, 1 >= eps, 1 > eps, t > - 1]
(%i24) integrate(1/u,u,1,a);
Is a - 1 positive, negative, or zero?

NEG;
Is a - 1 positive, negative, or zero?

NEG;
Is a - 1 positive, negative, or zero?

NEG;
Is a - 1 positive, negative, or zero?
-------------------------------------------------
I simply want to get Log(a) ...

My aim today:

integrate(1/t*integrate(1/u*(2*u/t-u^2/t^2,u,eps,t),t,eps,1)

with eps in ]0,1[.

Help appreciated :-p
Best,
Amities,
Olivier
