For any series X∞ n=0 a n, there are 3 cases: Ratio Test: Calculate lim n→∞ a n+1 a n = L if L < 1, then X∞ n=0 |a n| converges ; Root Test: Calculate lim n→∞ n p |a n| = L if L > 1, then X∞ n=0 |a n| diverges; if L = 1, no conclusion can be made. 2. Important Series to Remember Series How do they look Conclusions Geometric Series ...
Do individual terms involve fractions with powers of n? Do individual terms have factorials or exponentials? (Do absolute value of terms go to 0?)
