    Great solution. I’m used to seeing a square root of 2 in an answer; this time it was cool to see a square root of 3 appear.

    you know when someone mastered math when he's watching your video and all he does is the skip five second button the likes and clicks off. i was impressed when I saw him in the library today

    The new audio track feature translating your remarks into other languages is neat. I haven't seen that before. I checked out Spanish and Japanese. The voices sound natural rather than artificially generated. Cool. Expand your audience. Now back to the original from the start.

    where did you study advanced integrals, especially involving the gamma and beta functions? and,
    where did you do you high school schooling from?

      @@rishabhshah8754 I learned alot of math simply in the process of solving integrals 😂 just look for integrals to solve and you should be covered.

    How did no one in the comments realize you missed a factor of x squared in the numerator? Pleeeeease it pains me to see a solution development for an integral that is not the one at the start of the video 😭😭😭

    The result is correct, but the method of
    solution is wrong!!
    You have to avoid the non convergent
    integral
    \int_0^\infty 1/(1+x).
    In order to do that, split the integral \int_0^\infty
    (x dx)/(1+x^3) as the sum of the integral between 0 and 1 plus the integral between 1 and \infty. Perform the substitution t=1/x in the second integral to show it is equal to
    \int_0^1 dx/(1+x^3). Thus our integral equals to the arctangent integral
    (2/3)\int_0^1
    ((1+x)dx)/(1+x^3)=
    (2/3)|
    \int_0^1dx/(x^2-x+1)
    which can be easily computed.

    If the alternating sum is replaced by (1+x+x^2...x^2n), wolframalpha says it is not convergent. Is it right?

      split interval to (0,1) and (1,infinity), we have same result still
