I learned 2 new things from this video.
1. Infinite Geometric Series Formula. 
2. "Mildly Amazing Thing"

@izaanshaikh3999

I understood in 4.5 minutes what I couldn't in a 45 minute lecture. Sal rocks

@Hobbit183

So beautiful i have a tear in my eye

@alfieminto8972

1:46 Of course I didn't give it a go. The reason I watch your videos is because I'm too lazy to figure stuff out for myself.

@sixtysixx3933

First time ever Sal isnt repeating the sentences again and again. Maybe just a few times. Its just wonderful

@johnstewart6589

Iā€™m confused as to why someone would dislike this. Why?

@lokeshagarwal2406

This is really more than mildly amazing šŸ’•šŸ˜

@ishita522

And Congo for exhate 3600000 subs

@carolinewu5033

Thank you Sal!

@Hemsom1rojder

Awesome! I needed this to understand a proof that "e" is irrational.

@jelohsimo2435

Mind blown.

@AndresPuelloC

this video is nowhere to be found in the kahn academy website :(((( it interrupts the thread of Series. Anyway thank you very much for having all this available

@14tim4

The ratio could also be less than 0 but more than -1 right? So the common ratio can be -1<r<1 because any value between those will still result in a number close to zero when raised by a high index. Is that right?

@internationalremixes6440

One way to think about it!

@hellokat68

thanks, very helpful

@sonarammajhi7150

What will be the sum of infinite terms if      | r | > 1

@hunterzhong9308

why is it a r^n+1 rather than ar^n ? this is the only thing i am confused about,

@gilbertopelaez1624

Amazing

@ishita522

Nice one

@290647dj

Mindly mind blowing
