1. The problem statement, all variables and given/known data lim of (a^x-a^-x-2)/(x^2) as x->0 Find the value of the limit^. The answer is (lna)^2 I know how to get the answer using L'Hospital. However, I do not want to use Hospital's rule. I think I see the pattern with the special limit: lim of (e^x-1)/x as x->0 But I just don't see how I can apply that. I tried to take ln() out of everything, but it leads me to nowhere. Please help me.
