[TI, sin(x)^m*cos(x)^n] When m is odd... |
u = cos(x) |
|
[TI, sin(x)^m*cos(x)^n] When n is odd... |
u = sin(x) |

How to tell if a series is increasing or decreasing |
(a_(n+1))/(a_n), (a_(n+1)) - (a_n), (a_n)' |
|
(a_(n+1))/(a_n) |
If answer is 1 + (smth) --> increasing |
|
(a_(n+1)) - (a_n) |
If answer is positive --> increasing |
|
(a_n)' |
If answer is positive --> increasing |
|
Geometric series convergence |
abs(r) < 1 --> converge to a/(1-r) abs(r) > 1 --> diverge |
|
nth term test: result |
If lim(a_n) to inf doesn't equal 0, it diverges |
|
Integral test: requirements |
Positive, continuous, decreasing on [1,inf) |
|
Integral test: results |
If limit of integral of a_n is a number --> converge If DNE or infinity --> diverge |
|
Limit comparison test: requirements |
Positive terms |
|
Limit comparison test: results (for a_n) |
If lim(a_n/b_n) to infinity is a POSITIVE FINITE NUMBER --> a_n has same behavior as b_n Else --> inconclusive If L = 0 and b_n converges, a_n does too |
|
Alternate series test: results (for (-1)^n*a_n) |
If a_n is decreasing and lim(a_n) to infinity is 0 --> converges |
|
Ratio test: performance |
lim(abs(a_(n+1)/a_n)) to infinity |
|
Root test: performance |
lim((abs(a_n))^(1/n)) to infinity |
|
Ratio and root test: results |
If L < 1: converge If L > 1 of L = inf : diverge If L = 1 : inconclusive |
|
Power series: performance |
1. Find c 2. Conduct ratio test 3. L from ratio test determines where is converges 4. Endpoint - c = R |
|
p-series: results |
p > 1: converge 0<p<=1: diverge |
