OK, so I'm trying to work out this:
[tex] \int^{\infty}_a \frac{\dx}{x} [/tex]
Where [tex] a [/tex] is a positive constant. Can you evaluate this analytically? I'm thinking the limit must exist, but [tex] \ln \left( \infty \right) = \infty [/tex] , or at least tends to it in the limit. So can someone tell me the deal?
p.s. There's a dx ontop of that fraction, which has mysteriously disappeared into the abyss.
