New cards
geometric series
|r|
|r|<1 → convergent

|r|≥1 → divergent
3
New cards
harmonic series
always divergent
always divergent
4
New cards
test for divergence
if the lim(a) DNE or lim(a)≠0 → the series is divergent
5
New cards
integral test
only used if the function is continuous, positive, and decreasing

take the integral, then the limit
6
New cards
p-series
p>1; convergent

p≤1; divergent
7
New cards
remainder estimate for the integral test
where is f continuous, positive, and decreasing for x≥n and Σa is convergent
where is f continuous, positive, and decreasing for x≥n and Σa is convergent
8
New cards
comparison test
if Σa and Σb are series with positive terms
if Σa and Σb are series with positive terms
9
New cards
limit comparison test
where c is positive and finite and Σa and Σb are series with positive terms
where c is positive and finite and Σa and Σb are series with positive terms
