Intro to Geometric Series part 3

WHERE IS THE NEXT VIDDDDDD

[youdanaregood]

were is the next video

[joielock]

but why would you multiply it by r in the second place?

[Taimoorabdullah]

AWSOME!!!...... may i suggest u to get a White board..... and some erasable markers..... so u dont have to buy Pages all the time...... just write and erase...... the viewers can re watch the video if they miss something.........

[poyanator]

is that "r" the pro-numeral that is written below the sigma??

[vesaab]

saviour!

[BrightnessKnight]

Welll.. with this info i was able to find the sum of un = (-1)^n . (3^n/pi^(n+1))...

Thx a lot sir.. ;) .

One bit closer to getting an A on that final exame of Analysis.

[LikeItDeep]

Thanks. You explain things so clearly.

[utubsdum]

when you are doing the sum, you did

s=a+ar+ar^2+ar^3+.........+ar^­n-1 and multiplied by r, which gave u

rs= ar+ar^2+ar^3+..........+ar^n but had you continued s to ar^n and multiplied it by r, you would have gotten ar^n+1

[MrDrunklove]

Brilliant, I wish you would cover more maths topics. It's so much easier to follow on here than in the lecture. :D

[vin1236]

Great lesson, clear and concise, but when deriving the formula, but shouldn't it be a + ar^n-1 - ar instead of a - ar^n?

[franfred11]

I would love it if you were my maths teacher! you would be the best"

[franfred11]

THANK YOU SO MUCH FOR THIS!!!

[snowman3475]

Thanks for upload the video,I m most forgot those thing,and you make my mind clear.

[Tony1andonly]

You should cover the arithmetic series a bit more too! Part 2 totally answered this Q i had on a past paper about the geometric series. But now i'm unsure about a question about the arithmetic series which is similar to the question you answered on part, where they only give certain terms asking for the first term etc.

You should make more videos, we need a british patrickjmt, someone to make math videos for the UK!

[55akmed]

thank u very much that is excellent.

[lammy9463]

It's awesome, thanks very much

[Charlzz93]

thanks for the great vid! Ive missed quite a few maths lessons as of late, and this was a great way to catch up.

Thanks!

[Crunkmastaflexx]

pro

[LCaitlinK]

thanks sir

best homewok ever!

i actually think i understand it (after about 5 viewings LOL) and i will ask at least 5 stupid questions in the lesson ...

and this has totaly reuined my evening ... i will now be glued to watching stupid video's for at least the next 4 hours

[gilkesk]

i agree, keep posting please

thanks, maths exams soon

inequality geometric series would be helpful. like when Sn exceeds 200..etc

[Promi8]

thanks man...really appreciated it!

[THT1991]

goood job dude!

[xskylines]

this is really helpful, thanks.

[purpledragon613]

when do u use the formula?

[nafslee]

thanks

keep posting

[fchciutare]

well done
