Part ii), just sketch y= sin x and y = cos x and do subtraction of ordinates for y = sin x - cos x Part i) cos x = sin (x -a) Therefore we have sin x - sin (x-a) = sin x + sinx cosa - cosx sina And I dunno how to go from there. part iii) Just get it off your graph.

Alright, all you motherfuckers. English, whether you like it or not, is the mdeium of language for the country. Now, a lot of people complain, but we're doing English Literature. So what? You already know the fucking language. Do you really want to spend two years learning a language you already...

I have Transformations, and the texts are Clueless and Emma. Fucking gay.

Hornsby South (K -4) Waitara (OC Year 5-6) Just the average primary school =)

Lol Maths was the easiest exam. By them time reading time was over I had thumbnailed in half the answers. Our whole grade finished it in like 45 mins and spent the rest fucking around looking at each other.

3. x^2 + y^2 = 9 - Eqn 1 x + y = 3 - Eqn 2 From Eqn 2 y = 3-x Substituing this into Eqn 1, we get: x^2 + (3-x)^2= 9 x^2 + 9 - 6x + x^2 = 9 2x^2 - 6x = 0 x^2 + 3x = 0 x(x+3) = 0 x = 0 or -3 Sorry for the long and boring working out I wrote out every line...

I used to live in Hornsby, and Turra etc used to be easily accessible since tons of my friends lived around there, although I moved to Westleigh in year 4 Turra was still close and Pennant Hills was uncharted terriorty. Now I can walk around peeno with my eyes shut and know heaps about Castle...

Turra ain't far for me, but I doubt I'd be able to do it, Year 7s at your school are probably massive. At Ruse they're 4 foot tall nerds with a pole rammed up their ass. Very easy to monster, even for me, and I'm only 5 foot 7. This is the sad thing about James Ruse, every year is just getting...

I know a lot of smarmy Year 7 fuckers who think its their god given right to go to James Ruse. I would know, I'm a Peer Support Leader. The shit they talk, sometimes I just want to chuck them over the fence into the path of a car.

It's prelim for me atm. All my teacher has done is taken the basic Prelim course and jacked up the difficulty to Uni level in order to challenge the minds of James Ruse kids. This way, once HSC rolls around everything is dead easy. Also he's told us many times to not worry if we don't get it, as...

Differential Calculus - Price Elasticity of Demand, Cross Elasticity, Income Elasticity. Also involved in calculation of MPC and MPS. All involve some variant of dy/dx. Limits - The maximum amount of income is the limiting sum of the multiplier coefficient k and dY (change in income). Also...

Wow. I find Economics easy, but a lot of people in my class find it disgustingly difficult. It also has quite a lot of maths, so far I've learnt stuff that requires differential calculus, as well as limits. The theory is not difficult per se, but applying it can be if you're not prepared for...

Lol this test in easy. I've gotten High Distinction in both Year 9 and 10 with a precentile of 0.29 or something.

I sleep 11-6:30, So I guess I'm doing all right. Problem is weekends I can't sleep in either (swimming on saturday morning, tutoring on sunday).

Pie. I don't know. Pi is easier to work with. e is natural, like sex. So I can't decide.

1. I like either. Generally most smart girls are my intellectual equals, while slightly dumber girls always require help in their homework, and I am happy to oblige. 2. Don't care. 3. It doesn't matter I can link with both. But loud normally. 4. Outgoing easier to talk to, but I don't mind...

Why the hell do you think at 93+ Modern has insane scaling. Because it's much harder to predict the questions. In Chem etc as long as you know the textbook backwards, you rape it.

Textbooks: Maths - School uses Fitzpatrick for 2/3/4U. They also assign exercises out of Cambridge and Coroneos on sheets that they photocopied. I have all 3 at home. Chem - Conquering Chemistry. I also have Chem Contexts at home but it's more a supplementary textbook to Conquering. Eco...

My smallest class has 19 people. That's Modern History and Maths.

Maybe 30mins-1hour a night. Depends whether I have something due or to do or not.
