  • on the second one, could you have done root test instead of ratio? thanks

  • @jkomo15 try it and you can tell me

  • Thank you, thank you, thank you! You never fail me, I couldn't find any of the convergence tests on Khan Academy, but it's patrickJMT to the rescue!

  • @Pajameister tons of sequence and series (and other calculus stuff) here! come back any time

  • these are so helpful! thank you so much!!

  • no one on the internet thinks that people above precalculus need any kind of slow, simple explanation except for patrick JMT who just saved my life once again

  • Is it always the case to use a Ratio Test? ;x (Have not finished watching thru all the examples yet)

  • Thank you! :)

  • Hi Patrick! I have a question. What if the x function is squared e.g. -1<[(x-5)^2]<1. So how to you find the range of X

    Thanks by the way your videos are just awesome. Watch your videos is so much better than sitting in lectures which i dont understand.

  • @patrickJMT from calculus, that is

  • @darthmath2 i do like series, some of my favorite stuff

  • @patrickJMT Don't you just love power series? I am undergraduate level and I just love power series. I never found something so beautiful. I can't wait to further explores this at a graduate level!
