Comment (by jen):
Checking against 5.0.beta9, this looks good:
{{{
sage: var('a t')
(a, t)
sage: assume(a>0)
sage: assume(x>0)
sage: f = integrate(log(1+a/(x * t)^2), t, 1, oo)
sage: f
(sqrt(a)*x*log((x^2 + a)/x^2) - 2*a*arctan(sqrt(a)/x))/(sqrt(a)*x)
sage: f.subs(x=1, a=7).n()
4.32025625668262
}}}
