Easier to see now?
Hello, I have spent several hours stuck on this limit:
I managed to solve it by L'hopital, its limit is -0.5 but I was wondering if anyone can come up with a different method, as I am not supposed to use L'hopital at this stage.
But it did not work.
Any idea? Thanks!
Thanks for the reply.
I am allowed to use L'hopital's rule. But I am also asked to do it with a different method.
Given that in another exercise I had to expand ln(1+x) using a taylor series (which gives as a result the series abender posted) I think that is the extra way they want me to do it.
