Haha, 3U is tommorow actually on Friday. Im pumped for it.

Re: Year 11 2012 Chit Chat Thread We'll pull through :] According to some people, 4U is overhyped anyway.

Re: Year 11 2012 Chit Chat Thread I started the HSC 2U and 3U course last year at the start of term 4 as an official class. I did the preliminary courses in the first 3 terms of last year. (When I was in year 10) Since the accelerated course at our school started acceleration in year 9 where...

Re: Year 11 2012 Chit Chat Thread Nah my school only accelerates in math, but Im actually one of the last people in my school to accelerate 3U as the curriculum head decided not to continue that program anymore (2U acceleration of course is still going).

Re: Year 11 2012 Chit Chat Thread Oh wow thats alot of people heh. But in my school, there is a very low number of people who make it to 4U the 'normal' way, most of the people who do 4U at my school are pretty much 2U and in rare cases 3U accelerants. But I already have a very small 2U class...

Re: Year 11 2012 Chit Chat Thread At my school, usually about 4 or so people, however this year has 9 people doing it, and I think my math cohort is better than last year's one, so Im guessing we will have around 9 people doing it too. I find it weird that some schools have like 2 classes of 4u...

Well, 2U is simple in and of its self. And 3U tries to advance the difficulty by introducing more intimidating concepts, some of which are an extension of 2 unit topics, for instance in 2U, you only ever deal with One-Dimensional planes when it comes to motion, in 3U, you deal with 2D planes...

Re: Year 11 2012 Chit Chat Thread I cant wait for 4U Math.

Re: HSC 2012 Marathon :) I have finally found a solution to the question carrot posted, well here we go: Take the triangle in Carrot's diagram, within respect to theta: \cos {\theta}=\frac{x}{L} \\ \sin {\theta}=\frac{y}{L} \\ \\ \therefore x=L\cos{\theta} \ \ y=L\sin{\theta} Where y is the...

Parametric Representation is very easy, you just need to know knowledge from co-ordinate geometry and a sufficient understanding of the concept of both a parameter and of a locus. I reckon you should go over a bit for probability and do some Projectile Motion and SHM questions. Do the Past HSC...

Hang on the explanation of the diagram does not make sense, please post a diagram of the question.

Ok, I guess I can help then. I will post a solution within the next hour or so.

So people are doing your math assignment for you?

Me and everyone around me got 100 units, and the teacher marking it agrees. :)

Yes

I find it pathetic to try and cheat in 2U. I mean you could be wasting your time cheating on something else, and you decide to cheat on 2U. I mean, I dont even...

Yeah, and from what I've heard schools buy CSSA because its reliable as well as their 'good' tests. S&G > CSSA tbh

Its asking for an approximation so I put t=1.8 (approximate) Overall that question was indeed very poorly written and the graph was poorly drawn as well.

Ill be a very happy person if the CSSA 3U is about the same difficulty as the CSSA 2U (in respect to its own course). I am aiming for a 70/70 for this one, and will be hoping that it will be of similar difficulty to the past CSSA 3U papers.
