We were working with L'hospital's rule and my teacher said that the teacher before him told him that this was true:
lim (x→∞) [ln u] = ln ( lim (x→∞) u), where u is a continuous function.
My teacher has never found a proof for this, although it works every time. Does anyone know how to prove this? Thanks!
