(c) <- Cookie....

I havent done these in quite a while and i have one on my hw
Who can help me / find me a helpful site?

Thanks

 

[short recoil]

man, havn't done any sort of maths for like 3 years now.
Can't even remember how to do that.

 

[Shippi]

That hurts to look at I've never even seen those before

::Takes my awesome cookie back::

 

[Asknoone]

Can i have the awesome cookie. Pwease.

You can if you help ^_^
You don't happen to know summations do you..?

(Stoopid not remembering stuff i did a long time ago ><)

No. i just want a cookie ;(

I will take it in to see my Maths teacher...

 

[Shippi]

This thread is misleading You promised sweet, sweet cookies, yet all there is is maths! Which is not sweet, nor cookie-like ;(

and I'm sorry I can't help, I'm awful at maths. Worse than awful in fact

Yea, but if i put "Icky, unintersting math inside" Would you have still came in?

 

[joule]

Wow. What kind of math is that?

Math^100?

 

[Ikerous]

Wow. What kind of math is that?

Math^100?

Math 140
But i think these are also done in Pre-Calc...

 

[Tr0n]

Damn glad I dropped out...now give me that cookie bitch.

PM me your address and they'll be on their way ;-)

Maaaaaaaaaaaybe

 

[Ikerous]

Lol, i dont stand a chance of getting this answered do i... ><
Anyone know a good math forum?

 

[xLostx]

thanks, now im going to have nightmares

 

[Missingno.]

the answer is in that image...

you don't need much help from us :-/

 

[Ikerous]

Lol.. i wish...
The x sub i and delta x are just specifying what the variables are
You need to evaluate the limit...

 

[Ikerous]

Ooooh, im retarded!!! I think i know it now...
Thats the summation formula for integration
So that should be equal to the integral of x-x^2 from 0 to 1...

Okay, i think i've got it ^_^
You can ignore this now...
Either that or we can designate this thread to talking about how sexy tr0n is...

Or my leet new watch!

 

[kaf11]

now thats a leet watch if ive ever seen one.

 

[Ikerous]

now thats a leet watch if ive ever seen one.

Seriously! And it came in my cereal! ^_^
Free + leet = awesome

 

[B-MAn]

dude is that one of those questions on sequences and series?

if so then u have to use the formula

Sn = (n/2) * [2a + (n -1)*d]

S being SUM
n = being the amount of numbers
a = the first number in the sequence
d = the diffrence between each number

EDIT: ok no i;m wrong. its midnight here and i;m JUST startin my alevel physics work :x so i;m bound to be confused

 

[Triggerhappy41]

im in calc 1 and i forgot that stuff. i remember seeing it last year. gimmie an integral so i can feel better.

∫arcsec(x) dx

(That one is hard...)

∫ (1-x^2)^(1/2) dx

(This one is fun)

 

[Dan]

Has nobody here taken integral calculus? That essentially looks like the Reimann sum of a function as n approaches infinity. It's another way of calculating the integral. I'm assuming that they mean the limit as change in x approaches 0, which is the same as when n approaches infinitiy. In this case the function is f(x)=x-x^2. And the indefinite integral is that equation there.

 

[WacK]

LISTEN GUYS..! THE answer is!

Umbrella!

 

[Maxi]

MMmmmm integers...

I eat those for breakfast.

Cookie please

Spoiler

I suck at calculus but basically this limit converges to 0.

 

[Chris D]

The answer is 6.

You mean integrals¿•?

 

[Ikerous]

The answer is 6.

Close, its 1/6

Dan was completely right though
Man, that guy is my hero.

Its simply the reimann sum equivelent of
∫ x - x² dx and its from 0 to 1
(Its an area between two functions)

so ½x² - 1/3x³ |1-0
= 1/6

Its really easy, simpley a matter or realizing its a reimann sum -_-
