    Awesome video! This problem looks even a bit nicer in 2019, as you can go from 0 to 2019 and replace the 5 by a 1

    You should reveal the answers of some commenters AFTER the whole video, to avoid spoilers !!!

    Hi, I have a problem for you.
    find:
    limit of the integral of ((n^c)(e^-((x^2)(n^2)))dx) from 0 to c as n approaches infinity such that c is a constant and c>1.
    Does the function inside converges?

    good video.....now solve......integral limit( minus one to zero) ((x)^(4)-2x^(2))^(1/3)+√(1-√(x^(3)+1))

    Do you solve these while making the video or beforehand?

      @LetsSolveMathProblems I love the sense of spontaneity! Presupposing the audiences questions and confusions is really cool :)

      I always have at least one complete solution prepared for every weekly math challenge question before the problem is posted. In general, I spend around thirty minutes to a few hours of preparation time prior to actually filming a video

    Please can you explain fractional derivatives and fractional integral step by step

    • Math 1234
      Math 1234 10 months ago

      No I mean one half derivatives of any functions ......in general l mean m/n derivatives or integral of any functions

      Math 1234 you mean partial derivatives and integration by parts?

    Great video, I always enjoy these cool problems. Just one suggestion: Maybe you could show the first comment with the right answer at the end of the video or just show their name at the start. That way the answer won't get spoiled so early, which in my opinion would make the video more interesting to watch.

      @LetsSolveMathProblems You're very welcome!

      That is an excellent suggestion. In the next solution video, I will just reveal the name of the comment at the beginning and see if there are any downsides of doing so. If there are no viewers criticizing the new format (with a well founded reason), I will make the implementation permanent. Thank you so much for your helpful suggestion! =)
