    frick this guy has helped me so much. Wish I could send a letter or something just thanking him. I was struggling so much in calc 2 since it is so much more dense and you need to remember pretty much EVERYTHING from calc 1 and ALL other prerequisites in their most advanced forms and prof Leonard just goes through it so smoothly and breaks it down so well. On my first calc 2 test I received a 48, and then started watching him after that and on my second test I got an 85! Plus his sense of humor makes it even easier to watch and follow along with his lectures and not get bored. Prof. Leonard if you see this, I am so thankful for you, sir!!!!!!

  • @jonnymat1
    @jonnymat1 10 років тому +86

    Here's a little trick I use to remember when a Direct Comparison Test shows convergence or divergence:
    Just remember:
    1.) " a Smaller Cat"
    * When a(sub n) is Smaller & b(sub n) Converges: Converges
    2.) "a Bigger Dog”
    * When a(sub n) is Bigger (or larger) & b(sub n) Diverges: Diverges
    Hope this helped! I used cat and dog because it was easy for me to remember but feel free to use your imagination 

    I like his method of teaching so much because if I'm in the middle of a test and i forget if if something is a + or a - or if something is square root or squared, I know where it all started so I can figure it out. Instead most teachers make you memorize 6 equations when you could be learning this way and only memorizing the 1 that they were derived from and being able to derive them yourself.

From watching this great video and doing many problems from different Calculus books, I finally have an excellent understanding how to apply these two classical tests for convergence/divergence. This topic is also highly problematic for many students in Calculus Two.

  • @HunterNapier
    @HunterNapier 5 місяців тому

    Took a few watches to finally start understanding the difference in what we were taking the limits and working with tests against. Ultimately realizing first we test the SEQUENCE for divergence. If that goes to zero, then we can check the SERIES for convergence. If it doesn't, you're done. Also making sure to not confuse the value of the tests with the SUM of the series (way different things). Also dont make the mistake I did and start trying to find the sum of some of these. Turns out some (like the P series) looks REALLY tough. I think in all my tests we've only been asked for Geometric (because of the formula), and maybe telescoping sums because the terms cancel out. About 58 min into this is a really good "aha" moment recap that helps explain what we're ultimately doing I think. Good luck everyone!

    Question - For limit comparison, as an example take 1/n and 1/n^2. We know 1/n diverges (harmonic) and 1/n^2 converges (p-series w/ p>1), so we'd expect to find that lim as n approaches infinity of (1/n^2)/(1/n) does not exist, but lim n -> inf (1/n^2)/(1/n) = lim n -> inf (1/n^2)*(n/1) = lim n -> inf 1/n = 0, so that limit exists, which would suggest that either both converge or both diverge but we know that not to be true. What happened?

      I don't think you can leak any of materials that are intended for handing out to student because of copyright and risk of plagiarisms..
      Unless he has his own website that has purpose of posting lecture logs and anything related to his lecture

    imagine having that teacher and telling to your friend that you have got the best calculus teacher on the planet, but have got no evidence to prove it. thank god he just visually proves that he is the best ever

    I love that you state what the test is first and then ask "would you like a proof of this?" All of my professors do the proof first and I get so lost.

    He clears up sequence convergence vs. series convergence quite nicely @58:00. I would just like to add that in order for the Limit Comparison to work, the limit must exist (non infinity) and must be greater than zero.

    at 1:23:00, for those of you still uncertain about whether sqrt(n) increases at a faster rate than ln(n), take the limit of one of the functions over the other as n approaches infinity. If the limit = 0, the bottom function grows faster. If the limit = infinity, the top function grows faster.
