    Hi bprp, if you want some harmonic stuff: integrate ln(1-x)•x^n from 0 to 1 where n is an integer :^)

    But, what about the singularity at x=0 ?

    • @bain8renn
      @bain8renn 2 дня назад +1

      that is a singular real number point, and as such it doesn't change the quantity of the definite integral at all, because the reals are infinitely dense

    • @bain8renn
      @bain8renn 2 дня назад

      another way to think about this is, on the cut off versions of these integrals (from 0 to inf), using a right riemann sum approximation limit instead of a left riemann sum, so the first rectangle is defined with the right edge being located at f(x0), meaning the left edge would be at x=0, but wont ever be defined with f(0), as that is undefined. in the limit, the sum of "rectangles" are the smooth definite integrals, but you never used f(0) for any approximation rectangle, so the definite integral isnt defined using f(0) either, but it is still the exact area from 0 to whatever

    what is we divide something by 1/0
    for example
    4/1/0
    =4÷1/0
    =4*0
    =0
    is it right?
    pls don't say it is🥲.

    • @MatteoDolcin-ye8xm
      @MatteoDolcin-ye8xm 2 дня назад

      No
      1/0 Is undefined, you can't divide by undefined

      youd have to use a limit as otherwise this is still undefined, but in a limit this would be correct

    But if we don't use or rely on the properties of odd function, how do we reach the answer 0 if u-sub is used instead, like in the case of x^2025?🤔

    • @daniledenial
      @daniledenial 2 дня назад +3

      The boundaries of the integral will be from infinity to infinity since (negative infinity)^2024 = infinity, and when integrating from infinity to infinity it’s just 0
