Geometric Progression

[SlipUp911]

Great video, thanks

[JVNMChaitanya]

cool job.but can u upload any videos about electronics???

cuz i'm a bit weak in that part and u make me understand better........

[gsagula2]

are you on cocaine?

[ad92393]

wow. u talk faasst . u nervous dude?

[Denizen36]

Are you a teacher? Because Im pretty sure you can replace any teacher at my school, even the non math ones.

[burningyoutuve]

this is like 1 hour of class in 10 minutes that felt like 1 minute. shit! you are good

[Dewzy100]

thanx 4 the lesson, talk a lil slower and ud be the perfect teacher

[AkoVids]

slow down... xD ty

[2ndyearruby]

great.but you speak too fast..but thanks anyway :)

[SumerVsingh]

I loved your vdo...OK...Cheers !!

[xsqueetzzz]

You post great videos, where and what did you study?

[theshore465]

you are so adorable. i want to kiss you

[MsAllahhuakhbar]

why you have to speak very fast ah?

[th4Guy77]

thanks, my teacher cant even explain how to blink

[hackingtime88]

u going to tell us how to solve zenons series?

[tanvi766]

ur teaching style is jst bindaasssssssssss

[tanvi766]

its too goodddddddd

[tanvi766]

i watch ur vidio daily in morning or in evng!!!!

[tanvi766]

u'r teaching style is smthng diffrnt..

[tanvi766]

i like to see this vidio dailyyyyyyyy.....

i m a big fan of u..

[tanvi766]

mind blowing

[tanvi766]

if u were my teacher i will definatly get 98% becouse your way is so nice.

i am a big fan of you....

u are outstanding.

hattss oofffffffffffffffffffff

[tejasvi0claw]

*Hats off*!!

[TheNrubio01]

i speake spanish and only 1 thing for u

good work

[MrStankoman]

hi ! U again. Great video

[Fersomling]

I have a genius-level IQ and it is fun to see other gifted people.

[goPistons06]

thank you very much. i had read other texts concerning the sum of the terms, and your explanation is the best i've found. you teach very well, although you could slow down a little. otherwise, it's perfect.

[mytimeisnow17]

great!!!

tnx so much...........

[lphuff]

excellent work. you make it seem simple. i look forward to viewing more of your work. you have any work on elementary measure theory?

[donylee]

Nope sorry. No videos on measurement theory right now.

[melmabazza]

Too SPEEDY!!!

[SLYPA007]

Excellent work. 5 stars

[teamlk]

LoL, folded "Into Half" would be considered a grammatical error and redundant phrase in the Writing portion of the SATI. Regardless, this tutorial of geometric progression is outstanding.

[donylee]

I honestly don't know what's going on about 'folding a piece of paper into half 10 times' right from the get go. :-)

[re6ter]

if you fold a piece of paper 10 times it would reach the sun, proven by geometric progression

[monstrowhale]

err not exactly.. for paper stack to achieve the hefty thickness of 150 million km (distance to the sun) after ONLY 10folds, this sheet of paper would need to be 150,000km thick! geometric seq doesn't progress as fast as that, given that ur sheet of A4 is somewhere around 0.08mm thick. After 10 folds thus you will have only about 8cm.

However, as you keep folding the thickness will double every time, so 16cm at fold11, 32cm at 12, 64cm at 13 and so on. So u will need to fold it 51 times.

[troponinnutrition]

Exponential growth is often claimed as the most poorly understood mathematical concept.

The 50 folds to reach the sun concept is something people have a hard time putting their mind around.

[Semth1016]

well u got a small mistake.....

if u have an A4 sheet that is 0.08 after 10 folds it would .8mm thick

thats only if the sheet is 0.08..thick....so in order to get 8 cm...u will need to fold it 100 times or so :P

0.08*10=0.8

0.08*100=8.0

[monstrowhale]

You are just multiplying the thickness of the paper linearly, as if u stacked 100 sheets on top of each other. You are not stacking pages!! You are folding it double every time, so the rate at which thickness grows is not linear. Look at it fold after fold, given 0.08mm as original thickness: FOLD00: 0.08mm FOLD01: 0.16mm FOLD02: 0.32mm FOLD03: 0.64mm FOLD04: 1.28mm FOLD05: 2.56mm FOLD06: 5.12mm FOLD07: 10.24mm FOLD08: 20.48mm FOLD09: 40.96mm FOLD10: 81.92mm = 8.2cm after 10 folds only, not 100!
