Shouldn't (n^2-1)*n = n^3-n ? it doesn't change the answer but just in case

Let me check-at what timestamp?

[@danielaalvarex]

3:33 I noticed too

[@mathwithprofessorv]

@@danielaalvarexYes ok thank you for finally telling me where! Sorry for that boo boo-but yes; the result is still the same. 👍🏻 Good job catching that. 😊

[@pontshokgalelemagane1332]

Made a mistake at 3:19 prof on the numerator when taking the limit☺. I hope you noticed it . Otherwise thanks for the lessons prof

[@dayanaraflores8191]

hi professor v!! I am loving your videos!! I was wondering if you could do a part 2 with some trig?

[@mathwithprofessorv]

There is a part 2! I don’t remember how much trig is on there but check it out and get back to me

[@CarlPowell-rn3kh]

For the alternating series (n^2-1)/(n^3+1) why not just compare It with an alternating harmonic series and do a limit comparison test re which will prove convergence

[@mathwithprofessorv]

You can’t use LCT for Alternating Series, the conditions require all the terms of the series to be positive.
