I'd like help finding
lim
without the use of L'Hôpital's rule.
So far I did this:
\lim_{x \to 0} \frac{e^{2x}-1}{\tan x}
=\lim_{x \to 0} \frac{\cos x(e^{2x}-1)}{\sin x}
=\lim_{x \to 0} \frac{x\cos x(e^{2x}-1)}{x\sin x}
=\lim_{x \to 0} \frac{\cos x(e^{2x}-1)}{x}
Basically I got nowhere. Any hints or partial solutions to help me?
By the way, the is the 1969 AP BC Multiple Choice #28.
