HELP VESAYEN pass his math final tommorow!! If I do bad, I dont get to college

[Ecthy]

and about the same in the other 3 finals - compsci, politics, english(oral)

*standing ovations for Ecthy*

[Urban Ranger]

Wait till you got over 100%

[It is possible. All you need to do is to get all the questions right, and the extra credit question right.]

[MikeH]

Not possible in most UK exams. No extra credit questions.

[Ecthy]

same in Dtl.

I just finished my last exam that mattered (Economics unit 6)... Just praying I did enouhg for that A, after messing up Maths Last years maths was so easy, I haven't turned up for quite a few months Oh well, damn my overconfident self.

Good luck Vesayen. Where is it you're trying to get into?

[Ecthy]

790 out of 840, not too shabby

Go, go, go Andy go, go

but they would use different variables for functions
best example is this
f(x)=x+2
g(x)=2x
so then f(2) =4
g(2)=4
f o g (2)= f(g(2))=f(4)=6
g o f (2) = g(f(2))=g(4)=8
so you go from right to left
the memory trick is just to let ths o's disappear and glue them with parentheses like above
hope this helps

Just right to left?

What I thought-YEY! Thank you for confirming it though =)







say you have the term (2x+y)^4

so you start off by doing 2x^4y^0(which becomes 1)....

(2x^4*y^0)+(2x^3*y^1)+(2x^2*y^2)+(2x^1*y^3)+(2x^0* y^4)

thats to the fourth power, so you take the fifht level of pascals trinalge(one above the power, right?)....

which is 1,4,6,4,1

Now my question is WHAT do I do with that? I multiple each individual expression in that equation... I just multiple by the correspnding # right?

so (2x^3*y^1) is the is the secone term, so I Just multiply it by 4 to make it 8x^3*4y^1, RIGHT? heh

[Drogue]

Yes. The actual formula is called the Binomial Expansion and is basically the corresponding number from pascals triangle (nCr - should be on your calculator):

r!
---------
r! (n-r)!

multiplied by the example you gave above. So you get (2x)^4+4*y*(2x)^3+6*y^2*(2x)^2+4*y^3*2x+y^4 for your example above.

[Drogue]

Try http://www.mathsrevision.net/alevel/Binomial.htm if you want. That's the page about this. If n (the power) is not a positive integer (ie a fraction) then use http://www.mathsrevision.net/alevel/...tional%20n.htm instead.

The problem with providing assistance in a thread like this, is the thought that eventually there will be another thread:

"HELP VESAYEN pass his math final tommorow!! If I do bad, I dont graduate college"


To all of those who posted help, wouldn't it be ironic if this kid got hired to your company right out of college as your supervisor and then every week its:

"HELP VESAYEN get this report out by tommorow!! If I do bad, I dont get a promotion"


Honestly, Vesayen, I don't wish any ill will towards you. My point is that resorting to the internet to have your problem solved is a substitute for doing the brainwork yourself and it is almost like cheating. You would be better off if you did not resort to this.

You know any other kind of supervisor??

Feephi, I dont mean to have any ill will to..... actually I do: screw you .

Studying for weeks, few little last second things which I cant find in my notes, and I figured the nice(mostly...) people of apolyton could help with. If you think this is wrong, tell someone who cares-I dont and its rediculous for you to judge me over this.

Thanks for those who did give some help, going off to the test now !

Good luck

[Solver]

Feephi, you can actually let people do whatever they want, no?

Good luck Ves /

[Vesayen]

Update: I took the test, not ONE of the issues I posted about was on it lol! I think I might of gotten a perfect score-I'll know in 2 or 3 days.
