34
New cards

Choosing which test: 1. ratio

look for a clean ratio to the power of n

35
New cards

Choosing which test: 2. alternating series

look for (-1)^n

36
New cards

Choosing which test: 3. divergent series

look for a clean an

37
New cards

Choosing which test: 4. direct comparison and limit comp

ignore factorials

look for nice fractions

38
New cards

Choosing which test: 5. root test

look for equations to the power of n

39
New cards

Choosing which test: 6 ratio

look for factorials

40
New cards

radius of convergence three conditions

ratio(an+1) / (an)

< 1 interval converge

= 0 all x values

= inf only to center

center is where (x-a) in the function where a is the center

check end points by pluging in for x in original series and seeing if it converges or diverges
