I think using "bn = 1/sqrt(n)" in #2 is not a proper test because bn is less than an. Therefore, integral test probably will be most efficient. That said, thank you very much for the videos!
Hey, I have not seen you for a while. I can't pay for the tuition fees about it. I hope you can help me about this question. Question: Give 3 part formula for the area f(t) under v(t)

Thank you!!!
I had this doubt on which series test to use at morning and your video came just in time :)
Thanks dude, im a petroleum engineering student from Brazil and your videos help a lot! thank you very much sir. bprp calculus basics
Correct me if I am wrong but doesn't the first part (lim as n->inf of bn = 0) already guarantee the second part? at 8:05
You can have something like (1+(-1)^n)/n which approaches 0 but not decreasing. It goes up and down to 0.
@@bprpcalculusbasics I don’t think this alternates
@@TheMasterGreen that was for the bn part. So consider the series of (-1)^n*(1+(-1)^n)/n
You have to do this in calc 2? I did it at the beginning of calc 3
Thank you Thank you Thank you

I wish my exams had questions this easy
Thank you this was helpful
Number 15 you can use The Fact, right?
Correct!
I couldn't figure out 15 - What's The Fact?
@@vinuthomas7193 (1 + a/n)^bn = e^ab
@@vinuthomas7193 Ele está se referindo à variação do limite fundamental cujo resultado dá o número de Euler.
can you please elaborate what do you mean by The Fact?
can we use divergence test on the first question? since lim (n -> \inf) (n^2 + 1)/ (n^3 + 4)
otequal 0, the series diverges?
I dont think so, the lim = lim of (1/n+1/n^3)/(1+4/n^3) which equals to 0
@@manbican370 yes,i realised. By using l'hopital the term converges to 0. Thanks

what tests should I do on trig infinite series
like series n = 1 to ∞ (cos ^ (n-1) x
If x does not make cos(x)=±1, then the sum of cos^(n-1)(x) is geometric.
Where are you from ?
on your test do not add a sad face 😂😂😂
