okkkk, so we had thanksgiving week off. and we had a takehome test. i shall do some problems from this test.
1. a sub n = (-2/3) ^ n
you plug in values starting at one, then two, three, etc...
& find your answer.
2. determine the convergence/divergence of the sequence with given nth term. if the sequence converges, find its limit.
a sub n = 3^n/5^n
geometric test. rewrite as (3/5) ^ n.
abs. value of r < 1 then it converges. 3/5 = r. after that, take the limit of the original problem. & it converges to that #.
these are just some examples. can someone explain integral test to me?
