there is never any parks at newcaslte uni!! does anyone know of a way 2 get a staff sticker, i'm sure they'll b sumone willing to sell theirs ? or of any good, but unknown parking spots?

oops. spam retracted!

ONline TEXT game. GREAT FUN! [url]http://www.kingsofchaos.com

our teacher showed us this reallly really long method of proving the reflection property of the ellipse and hyperbola. i was wondering if there was an easy, preferably, quick method. ???

nd that's not really u is it?

nope our teacher alwasys lets a=o then solve for v. cause when there is no acceleration it is at max velocity. u know that from 3 unit (SHM)

nd i don't understand this: (a_1+a_2+...+a_n)/n >= (a_1*a_2*...*a_n)^(1/n), where a_1, a_2,...,a_n are positive integers. what the hell does underscore mean?

o is that all. most questions tell u that anyways. i thought it was something to do with that physics equation; escape velocity= sqrt of 2GM/r

the arithmatic one is easy, knew that since ... a long time ago, but how do you work out the gp one? Tr in a geometric series is ar^n-1 right?

"- Know how to work out escape velocity using inverse square law for gravity" please explain. i always get escpae vel q's wrong, and coincidently i don't know the inverse square law u speak of

"For inequalties you must know the arthimatic and geometric means identies off by heart" so what are these again?

well i also would like to know. one of my friends e-mailed it to me said he couldn't do it. like someone else said- i really don't think this is hsc style.

no its all kool it was a cubic. y = (-1/12)x3 + (13/12)x2 - (8/3)x + (14/3) thanks guys. p.s no parabola works

ok man i did it, and got what u got. thanks (p.s that did take a loong time) but good practice for my algebra skills
