Ratio Test:
When does it converge & diverge & is inconclusive.
if the lim n-> ∞ < 1 then the series converges
if the lim n-> ∞ < 1 then the series Diverges
if the lim n-> ∞ == 1 then the series is inconclusive
P - Series:
When does a series converge, and diverge.
The Series converges if P> 1, diverges if P <= 1.
Divergence Test:
When does it converge & diverge & is inconclusive.
of the lim n-> 0, then the test is inconclusive.
Direct Comparison Test:
When does a series converge, and diverge.
- If 0≤an≤bn (bn converges then an also converges)
- If an≥bn≥0 (if bn diverges then an also diverges)
Limit Comparison Test:
What is the formula for the test?
What does L have to be to converge?
What does L have to be to diverge?
If L is a finite positive number (0 < L < ∞)
Both series (an) and (bn) either converge or diverge)
If L = 0 and Bn converges
An also converges
if L = ∞ and Bn Diverges
then An also diverges
Alternating Series Test:
When does it converge, and diverge?
When Lim n->oo an = 0
