Question

Help. Help. @Mathematics

Answer 1

what is this ?

Answer 2

No idea.

Answer 3

geometric series?

Answer 4

Infinite, Convergent & Divergent Series

Answer 5

what is 6th partial sum?

Answer 6

no idea.

Answer 7

yeah like it kind of looks like (a)(r)^n

Answer 8

Could be .. I am yet to study sequence and series in detail.. :(

Answer 9

Answer only. :D

Answer 10

as that comes right after those covergence and divergence stuf

Answer 11

so no1 knows it. :(

Answer 12

i'm looking at it it's been a long while

Answer 13

:/

Answer 14

thanks for trying..

Answer 15

you could move it up and use a geometric series lol

Answer 16

LOL

Answer 17

I guess I got it!! :D

Answer 18

Yay! :D

Answer 19

got what?

Answer 20

did you do 4 yet those are super easy

Answer 21

no, i just did 1st one..

Answer 22

http://www.mathwords.com/n/nth_partial_sum.htm

Answer 23

rest 4 are here.

Answer 24

4 is conergent

Answer 25

i dont want to learn them man!
just give me the answer. :/

Answer 26

4 = option?

Answer 27

lolz saifoo that's not a good thing :P

Answer 28

lol, c'mon.. sometimes it's good.

Answer 29

it's convergent however that n-1 is throwing me off because the formula is ar^n

Answer 30

:/

Answer 31

I think that 5th one is not convergent ..

Answer 32

it diverges |5|>0

Answer 33

>1 i mean

Answer 34

yeah ....

Answer 35

so, question 5, option B or C?

Answer 36

1335 number 1

Answer 37

4 is B

Answer 38

B for numer 5 if its 0<|r|<1

Answer 39

is not satisfied

Answer 40

5 is also B

Answer 41

again thanks I learned a new terminology :P

Answer 42

4 is also B

Answer 43

saifoo for the partial sums i'd just use an integral

Answer 44

from 15 to 1

Answer 45

^^ right that would be a good approach !!

Answer 46

later on you find out you can use integrals to find the sums of series.. .which is basically what area is

Answer 47

^^ that has some beautiful use in probability theory too .. ;)

Answer 48

Q 5 = b

Q 4 = b.

question 2 and 3?

Answer 49

3 is 1246

Answer 50

Thanks btw

Answer 51

=D

Answer 52

Q 2?

Answer 53

any guesses?

Answer 54

still working on it... trying to find a way without having to actually tally each one u

Answer 55

could use a integral again XD

Answer 56

hold on

Answer 57

=D

Answer 58

ty

Answer 59

saifi, stop being lazy :P

Answer 60

Mini go to sleep.

Answer 61

Answer 62

Stop being a hypocrite, you shoul go to sleep

Answer 63

LOL, im not being that.

Answer 64

Fine then douchebag

Answer 65

hmm this seems weird cause #2 is a geometric series that diverges

Answer 66

saifi, any examples ?

Answer 67

outkast, any doubt? i will go for it.

Answer 68

well i did it one by one and i'm still not getting an answer there

Answer 69

Answer 71

stupid notations...

Answer 72

i will brb in 5mins.

Answer 73

9555 is answer for #2 ... just not sure how they did it without doing each and every becuase the geometric test only works for when |r|<1

Answer 74

and you have 4 there

Answer 75

Q 3 went wrong, rest all correct. :D

Answer 76

whbat did you put for number 3

Answer 77

i keep getting 1246 using an integral
