# Solveable without L'Hopital's rule??? watch

1. Hello,

I haven't yet learned L'Hopital's rule, but I was vaguely aware of it. I tried to solve this question using just the fundamental limits, but got nowhere. I then googled what this rule was, and solved the problem in a few minutes... So my question is, is there a method without differentiation I could use???

Thanks

Series expansion would cover it.

, I presume you're familiar with.

can be rewritten as and use binomial.

Sorry I don't understand what you mean? do you mean the Taylor thing?

Maclaurin series, which is the Taylor series at x=0

Ok we haven't covered that yet, just glad to know there isn't a method using what I know already!!

Thanks
