Q: Use L' Hospital's Rule, when you convert your expression to a fraction, check and state that the hypotheses of the theorem are satifsied.
Find limits. Use L'Hospital's Rule when appropriate. If there is a more elementary method, you might consider it.
limx→1 x^5-1/x-1
limt→0 4^t-2^t/t
lim x →1lnx/sin(πx)
