    Thank you for breaking down all the thought processes, especially about finding a simpler function for carrying the convergence test [5:15]. Also great job about the way you use the colors ! That really helps to drive the attention toward the main aspects of each situation. I love your work !

    Nice video! You explain this stuff extremely well.
    At 6:32, we can use partial fraction, and arrive at -ln|x+1| + 1/2ln|x^2 - x + 1| - 1/sqrt(3)*arctan(2x/sqrt(3)) + C.

    I know I am a bit late but I still wanna ask you by the comparison test we deduced that the following fraction will be less than 1/x² but we hadn't checked if the fraction was bigger than 1/x .. So, to my estimation we should've checked if the fraction was bigger than 1/x..
    I might be wrong but please clarify it me..
    By the way awesome videos now I am learning the calculus from your videos without anyone's aid..

    • @EdgarKirakosyan.2005
      @EdgarKirakosyan.2005 6 месяцев назад

      nah, you must be keeping the biggest power of x in place, it is always better to go logically towards the smaller/bigger function, but DCT (the test described in the video) is actually a little hard because it needs good algebraic knowledge and concentration to find the other function compared to LCT (limit comparison test) where you take any function and simply calculate the limit of original function over your function and prove that they are connected by getting g a positive value
