      Don't think that such an integral exists, can you give us some background as to where you found this question and if it was a definite integral before because I just checked on wolfram alpha and it seems this doesn't have an elementary anti derivative.

    • @reetasingh1679
      @reetasingh1679 6 лет назад

      @@emperorpingusmathchannel5365 Even with the chain rule, the function appears to be non elementary... Even ln(ln(x)) is non elementary I believe, so 3 nested lns will almost surely be non elementary

    • @PackSciences
      @PackSciences 6 лет назад

      That's typically what computers are for.
      A trig function raised to the 251-st power will have at least 251 terms; which is not good for a video.

    Hey #BPRP
    I have a contradiction that i found weird
    We all know the proof that the some of all integers =-1/12
    I have one that =-1/8
    Which is not a joke
    And i am confused right now
    So i want an explanation for them if you know both
    If not tell me how to send them to you and probably answer me...
    Merry Christmas 🎄🎁💕
    Thanks for your care.

      Thank you. I wish you happy holidays too. I know how to get to -1/8 as well. 1+(2+3+4)+(5+6+7)+(...
      =1+9(1)+9(2)+....
      And you can get to -1/8 from here
      Don't we just love divergent series : )

      Does not this lead to + 1/4?
      1+(2+3+4)+(5+6+7)+... = 1+9(1+2+...) = 1-9/12 = 1/4
      How do you get to -1/8? Now I am confused too.
      Ah now I see. x=1+9x => x=-1/8.

    Greeting Caoさん, I challenge you to do the same except in Chinese. If you know other languages, then you can try them out, or use Duolingo right here: www.duolingo.com/ Duolingo is a free language course that allows you to learn lots of other languages, over 30 languages total! By using this tool, you can be able to share with your content all over the world! I know that the hashtag is a partially extinct, so why not just put in #YAY for rest of the people in the comments section? Thank you for reading!
    Best Regards,
    Alex E. Gonzalez
    P.S. There's your clue, I'm not actually Einstein, though I have a passion for physics. I am also called by Japanese alias Ryuyogen Naruhodo, or Chinese alias Longyuyan Chengbutang, with the same characters (成歩堂龍預言). I know that you may know this, but for those that didn't, you can find more information about me in the "About" section. Again, thanks for reading!
