comment Nonexistence of a limit
This does not say that the limit does not exist. It states the condition for a given L to not be the limit. If you'd want to show that the limit does not exist, you would have to do it for all L as well

@Asydot you are right, I guess I only tried the indefinite integral on wolfram.
