You always get your own exam mark that you score in the HSC. However, if you remain last, you'll get the lowest exam mark out of all three people (you and the other two) as your moderated assessment mark.

wut?

It seems so lengthy though... How about this: \int \frac{x^3}{2x+1}dx =\int \frac{\frac{1}{2}x^2(2x + 1) - \frac{1}{2}x^2}{2x+1}dx =\int \frac{1}{2}x^2 - \frac{\frac{1}{4}x(2x+1) - \frac{1}{4}x}{2x+1}dx =\int \frac{1}{2}x^2 - \frac{1}{4}x + \frac{1}{8}\times \frac{2x+1 - 1}{2x+1}dx =\int...

\frac{(sinA + cosAtanB) \div cosA}{(cosA - sinAtanB)\div cosA} =\frac{tanA + tanB}{1 - tanAtanB}

3U topic. 1. cos2A = 2cos^2 A -1 Use that. 2. Divide LHS numerator and denominator by cosx.

Re: HSC 2013 2U Marathon I hope you didn't perform polynomial division :P If you didn't, it's the same technique applied to the 2nd question.

Price elasticity of demand is the percentage change in quantity demanded that results from a 1 percent change in price of the good/service. Say we had a highly elastic good that was selling for 10 units for $10 each. If we increased the price to $11, the quantity demanded could drop down to 2...

Re: HSC 2013 2U Marathon \int \frac{x}{\sqrt{x-1}}dx (no substitution.)

Re: HSC 2013 2U Marathon \int \frac{x^3}{x^2+1} dx what's wrong with my code ._.

Re: HSC 2013 2U Marathon This question would trump 3U students lol. Possibly the average 4U student too.

Depends on your school. Scaling was applied to one of my trial exams at my school.

33/50*

Do 2 speeches in depth and have an essay prepared for them. Make a paragraph for every other speech on a theme/common idea that links to either one of the two speeches you studied in depth. Saves time and you can talk about 3 speeches in an essay if they specify one (unless the question is...

I don't think it's possible to "drop straight to commerce" as it's now a separate degree. From the UNSW website: Have a look at this page if you haven't already: https://my.unsw.edu.au/student/academiclife/program_transfer/InternalProgramTransfer.html

Need any help? Msg me :) I think they do consider your WAM even for first year students. I've heard it's much easier to transfer within your uni than applying to another.

Bump

Hopefully i got this right.

Enjoying maths and it doesn't require much study so i'm happy about that :D Also enjoying actuarial science, less than maths though. Eco comes after then finance which is just boring..

\overline{x} = (x, y, z) = (3, 2, 0) + \lambda (1, 2, 3), \; \lambda \in \mathbb{R} x = 3 + \lambda y = 2 + 2\lambda z = 3\lambda Not in the HSC.

Know EVERYTHING back to front. Know how to answer all types of questions (discuss, explain, deduce, assess, etc), working on structure, and being able to communicate clearly and concisely. Do past papers (that have solutions) under test conditions and mark them strictly. Was there anything...
