here's a part of a question from my trials today which I believe to be incorrect: P(x)= x^5 - 5cx + 1 Prove that for c > (1/4)^5, P(x) has 3 distinct real roots. Any ideas?

and for question 2: find all the angles you can find.. start with angle C :)

I am doing mine on wednesday confidence booster -> get a stack of past papers do questions 1 and 2.. then just do questions 7 and 8, allow yourself some time.. make sure you don't give up, after 20 question 8s you will certainly not be afraid of any paper.

hmm.. works with my teacher, Everytime you see her giving a seven mark, it will be full of jargon.

band 2 means a pass.. so 50%, which shouldn't be too difficult if you put in some effort. Go in the HSC, sit for three hours and do what you can, that should get you badn 2 EASILY

Measure with a ruler or for accuracy, use a micrometer gauge.

diag tests in arnold are precisely there for their proclaimed purpose - to discover you weaknesses, not really for practicing or polishing. Yeah, do practice papers, after learning everything in the book.

You're not alluding to one of our greek friend's work are you.

By the way, can't you just prove the shell thing, by seeing the shell as a slab Dx thick and 2Pi*x * y in size folded into a cylinder? Fitz patrick and some other books do it that way.

Your school's careers adviser should be informative on this. You could also take a Diploma course from TAFE and then transfer to a university with advanced standing, But it's only for very few courses (businessish or IT related usually) and not for every Uni so yeah, repeat the HSC is the...

according to what I know, you have the right to know your rank

Very High Exam mark; eg 98 probably better with 1st in a comprehensive highschool :p But chances of getting a 20th in school and such a high mark is slim

trials 50+ HSC 50+

*Definitely*

^^ Oh pappus's theorem :P the center of the shape means the centroid SO.. WHAT THE... are we meant to derive the integral for spherical shells every question? *faint*

Ofcourse 4U is hard... When most of that comes from ppl who don't even do the course. I agree with eszty, take a try. It's easier if you stay ahead of the class by reading and trying to do as much as you can before the teacher teaches.

it's in the course.. think it's in the 3U course.. Anyway, Just because it's not in the course doesn't mean it's not mathematics.

I think your instincts should lead you to the solution, just flip through the book, go through the theorems and "important" points
