Squeeze Theorem

If g(x)≤f(x)≤h(x) and lim as x→a g(x)=L and lim as x→a h(x)=L, then lim as x→a f(x)=L

If the denominator grows faster the horizontal asymptote…

is at 0

If the numerator grows faster the horizontal asymptote…

does not exist

If the denominator and numerator grow at the same rate, the horizontal asymptote…

is the leading coefficient in numerator divided by leading coefficient in denominator

L’Hospital’s Rule

If f(a)=0 and g(a)=0 and the lim as x approaches a of f(x)/g(x) equals 0/0 or infinity/infinity, then the lim as x approaches a of f(x)/g(x) equals f’(a)/g’(a)
