Intermediate Value Thm. A function f(x) that is continuous on a, b takes on every y-value between
f a and f b .
Extreme Value Thm: If f(x) is continuous on a, b , then f(x) must have both an absolute min and absolute
max on the interval a, b .

Direct Comparison
Limit Comparison
a series with terms smaller than a known convergent series also converges
a series with terms larger than a known divergent series also diverges

if lim n is finite and positive both series converge or both diverge
