Strategy for Testing Series - Series Practice Problems. In this video, I run through 14 series problems, discussing what I would do to show they converge or diverge. I try to show what I think about when I look at a series, and what 'sticks out to me' as to how I should justify things.
I DO NOT WORK ANY PROBLEMS OUT IN THIS VIDEO!!!

  • for number 4 I cant seem to get it to converge when I split it up I get 3((-1)^n)((3/8)^n) which goes to infinity when you test if the limit it goes to zero

  • @jeffschroeder43 i think my intuition was wrong on one or two of them; you may read the other comments to see what others think

  • I think I'm gonna watch your calc 2 playlist before I start MV calc next semester = ]

  • @ICarnag3I sounds like a not terrible idea ; )

  • Great video. Did you post solutions to these problem by any chance? :D If not, are you going to be making one?

  • @jamesa07 no and probably not : ) i have a lot of sequence and series quizzes and solutions on nixty dot com if you are interested

  • @plbernstein92 It depends if the original series is alternating or not i think. Since the ratio test already takes the abs value of the series it solves for all the positive values...if the series before abs value is taken is still all positive there is no chance of it being conditionally convergent....my calc 2 final is wed.

  • @porkystarcraft if i'm not mistaken, since it diverges by the ratio test it could still conditionally converge. Patrick, can you please address this one: my test is tomorrow morning!

  • @Billabong024 I got the same answer as you did.
