diverge, approaches -infinite
diverge obviously
i knew it
do you know the interval of conv. though
im having some trouble
/fitlit/ still lives
lol idk dude calc II was like 5 years ago. wolfram it
depends on x. Hint: it's a geometric series.
Use Cauchy theorem, I don't know how to say it in english. and then develop it like a normal equation. simple as fuck you brainlet
Thanks for reminding me to do some homework instead of lurking Veeky Forums
ight nig
yeah abs value of x is less than 1
I thought converge means it appoaches minus infinity and diverge means plus infinity
wtf is that lol
nah i think i got it. Its divergent on both ends of its conv interval because r>1
no nigga
what? they don't teach you this in US ??
en.wikipedia.org
it's much simpler to use these Theorems, I did it in 5 sec
ohh nigga isnt that the gay ass root test
fucking hell the numerator needs to be smaller than the denumerator for it to converge you nigger
I dont know how you call them inegrals, but i know fo sho when we did them we would solve a limit and we would then conclude based on what it approached at the end
Man, there are 2 theorems that you use with that shit.
D'Alambert, and Cauchy. How do you call them, division and radical?
Anyway, with D'Alambert you'll find that the interval of convergence is
>3 +- 11/3
if you can't solve it yourself you don't deserve any scientific degree.
I had my last math class 5 years ago, and I know the answer just by looking at it.
correction, the ratio should be smaller than 1, thats what i meant
turns out im the nigger
Let's pretend that i'm a brainlet.
WTF am i looking at and how do i solve it?
you nigger
after you do the root test you can find r
r turns out to be greater than 1 so it diverges
so you dont have to test the end points
yeah thats the same shit
maybe you should stop memorizing everything and start trying to understand the intuition behind it
why would you use the other one when its to the nth power
fucking nigger
thanks you niggers
looking at some easy 2nd semester math.
OP needs to just pay attention in class or read the texts BAKA
what's with all the niggering in here?
stfu no one is handing out scientific degrees fagget
this class is a preq
2nd semester of what, university? It looks like cuneiform. I need a walkthrough before my brain melts from being unable to process this data.
what is this type of math problem called? Geometric series?
its basic calc
yeah or power series
why can't you faggots ever post the fucking problem oriented correctly? kys highschool retard
suck my cock
This is not /fitlit/. This is definitely /fitsci/.
kay I am really bad at math but what you write does not make sense to me
it's an infinite sum of basically (-x+c)^n so how it develops depends on x, which I dont see defined anywhere maybe because I am blind
so if x is 3, then it's an infinite sum of 0^n. 0^0 is undefined, the rest is zero
if x3 then the entire thing is negative so basically (-y)^n
now what matters next is if the number in the bracket is less than +-1
11/3=3+2/3 so the value is +1 at -2/3 and -1 at 6+2/3=20/3
so if -2/3
Are you actually retarded?
ehhhhhhhhhhhhh
this thread is dead
problem is already been solved.
