I said that someone else can do it i haven't covered the HSC topics yet, nor have i even started year 11 yet, but i like to have a go at some things, this looks to hard. but: for the derivatives of the two particles you get the velocity. Not sure if thats right but thats all i'll attempt...

This is the 1995 Maths 2/3 unit common paper, question 10. If only i had those solutions.

Nah, i cant work it out. So my above post is invalid. ok someone else try it.

See my sig#

How the hell do you find that! Oh wait do you use integration! i think i know what to do. i might have a go!

Post the next question up then!

Riviet I dont have a text book, as I haven't started year 11 2006. only an assignment from orentation day

it's the identity; sin^2 θ+cos^2 θ=1 so when you consider that whats in the brackets is actualy an angle it directly refers to this identity. hows that!

Relate some major features of the universe (eg.galaxies, superclusters of galaxies, planitary systems, backgroud microwave level. ect.). Where could i find out this information?] Thanks in Advance

So if the primitive of X^n is x^n+1/n+1; then the dirivative of x^n is dy/dx=n.x^n-1 is that right. But what does with respect to x mean, i've seen it alot.

Cheers Riviet!

I've tried teaching myself integration but i dont know where to start, like what was the first part of integration that u guys learnt. (antideriviative/indefinte integral) or what!

A=A0e^kt is the solution to this question but i dont know how to use the formula

This is dN/dt=k(N-P) and it is a extension 1 topic at my school. the solution to this equation is N=Ce^k-P or something...

No well our school head teacher for science said 26 assignments throughout the year for physics, and chemistry is more.

Well just looking at it at a glance it's about 20 questions in length and contains cell division, DNA, environments,habitats, communities, ecosystems, food webs, aboitic, and biotis features. Fossils, Evolution and natural seclection, continental drift, and plate tectonics. And two experiments...
