Geometric Series - Sum to Infinity : ExamSolutions

[@footballnerd277]

Anyone else love the 'surprised' wow at 3:44

[@sadmanzaid420]

I play it at 0.25x speed.

[@ExamSolutions_Maths]

Thanks - pleased I could help you.

[@iilogic]

Had one exercise I could not understand because our teacher never explained it to us. The video had exactly what I wanted to know, and the calculator was the same one I have (only mine is not a computer program, but the actual thing) so I also learned a couple new things about it (haven't familiarized completely with it yet). Helpful, well explained video, Thank you!

[@solidsmuffins4776]

when that calculator came up I shat myself

I don't know how or why but this comment made my day! :)

[@ExamSolutions_Maths]

Thank you

[@niccolo7977]

Will you still make more videos for CIE ?

[@nnennaokikeuzor6165]

Actually The Organic Chemistry Tutor is the best teacher on KZbin

This was a good tutorial for deriving the formula,,thanks

[@aywt]

Great video thank you so much:) you explain everything so clearly! better than my teacher actually xD

[@benoftheweek]

Math makes me want to drink Windex

[@richardlighten7076]

fantastic video , clear and easy to follow , thanks

[@Mooncake69420]

The more i think about it the more it seems like some one is walking towards a point and every time he reaches half the distance, the distance he needs to travel doubles or he gets half the size and thus his steps are coving half the distance as before. So every time he travels 5 meters of 10 meters he needs to travel he shrinks then after he travels another 2.5 meters he shrinks then after 1.25 he shrinks and this keeps on going till infinity. If that is so wouldn't the actual value be x

[@taniwha5441]

Holy shit that's a good point

[@ExamSolutions_Maths]

@jony1710 you are most welcome

[@ExamSolutions_Maths]

It was purchased from Oxford Calculators (Google them)

[@hansh_0181]

Thank you sir

[@ExamSolutions_Maths]

You are welcome

[@xDivineForYou]

thanks man love your teaching

[@manojkumarsubramaniam7122]

the common ratio should be absolute value of r < 1

[@ExamSolutions_Maths]

@thebest1870 Thanks - hope it goes well for you.

[@IanChingMusic]

Hey! From where did you get that calculator?

[@Sunlightphil]

~ WOW ~ Thank You :)

[@4747xavy]

brilliant!!! thank you

[@Slimycat90]

is this video about limiting values of a sequence? For example: work out the limiting value of this sequence as n approaches infinity: 2-6n/5-2n

[@wyrwshwsrey463y]

what if the common ratio is more than 1? or less than -1? do I need to change anything so that 'r' is IRI

[@Shariqwaseem]

Can you tell which software are you using as a calculator? ThanK you.

[@ExamSolutions_Maths]

It's a casio emulator. Just Google it and you can but it from Oxford Calculators.

[@misan2002]

Shouldnt it be 0

[@rosette_renah]

Nope,,its-1

[@fazila8583]

Thank you so much really helped Boms n Fazila from Portsmouth Uni Uk

[@ExamSolutions_Maths]

That sounds good.

[@ashlikaeandra9348]

All the way in Jamaica preparing for my A levels, in need of urgent help on this problem. Find the sum to infinity of the following series 1/4 + 2/(4^2) + 1/(4^3)+2/(4^4)...... I know it can be written has the sum of two geometric series but I have not been able to get the correct answer. PLEASE HELP!

[@claraishungry501]

i know im 7 years late. how were your a levels?

[@iilogic]

Well, thank you kind stranger, I just finished my quiz and got 100% ^_^

[@ExamSolutions_Maths]

@Alexraza1 I would show the part on the right

[@ExamSolutions_Maths]

@ragheneration Sorry, no

[@ExamSolutions_Maths]

Cool

[@chrisdrew1060]

Like like like like like it really helped a lot

[@Mooncake69420]

@ThePsycheoutFanClub I mean, it would definitely be tempting to say he traveled exactly 10 meters because the thought of "going on till infinity" would make you think he would have reached the destination at some point, but the truth is that he will always be an infinite fraction away from the destination at all times no mater how longer he walked his steps would just shrink again, know what i mean?

[@noahark3863]

I'm new on this site

[@ExamSolutions_Maths]

+Noah Ark Well I hope you find it useful.

[@andreasntoulos]

Ok but if | r | > 1 or better r > 1 ??? wouldn't the sum of infinite summands be infinite? a = 1 r = 1.57178 ?

[@ge2719]

+MrSantaCla exactly, thats why you can only use the sum to infinity formula if -1

[@blainefoster12]

MAGIC

[@paanazmi8062]

how to get scientific calculator on screen?

[@Sachie94]

Khan's academy :) just look it up here on youtube, and you'll fin loads of videos :)

[@BushaaroClaahi]

How is (1/2)^50 is zero??

[@king-bg4rp]

very small value so calculator considers it as zero

[@GameDeva7171]

thanks😑😑🇳🇵🇳🇵🇳🇵

[@ankanbasu1415]

5/13+55/13^2+555/13^3+.......to infinity can anyone solve this...

what if the series is going in an increasing order
