Let the roots be @ and @+1.

someth1ng can't count - there were 44 awarded that year.

I also received a USYD entry scholarship (which I later declined due to another scholarship). You just need to demonstrate that you're not just another nerd who studies all the time. Extra cirriculars, amazing experiences and general interest/passion goes a long way. someth1ng is incorrect...

b) A projectile is accelerating at a constant rate of -9.8ms. If it is initially 2m high and has a velocity of 4ms find the equation of the height of the projectile. \frac{\mathrm{d}^2x}{\mathrm{d}t^2} = - 9.8 \Rightarrow \int \frac{\mathrm{d}^2x}{\mathrm{d}t^2} \mathop{\mathrm{d}t} = \int 9.8...

Often writing out your interpretation of what is given in the question can be a good starting point for many problems. E.g. '...it is given that ___ is a root. Find the relation between ...' So you'd think: ok well if it's a root, what does this mean? Well if I substitute it into the...

Re: HSC 2013 4U Marathon As I said...just use the align or eqnarray function...~~~~~~ is a manual function that is the antithesis of LaTeX.

But... I do discrete maths...and you hate me... so...

Re: MX2 Integration Marathon Oops yes I can't factorise :P

Re: MX2 Integration Marathon \frac{1}{2}\ln 2

Wrong. Men were, are, and will always be indebted to women due to their eternal discrimination.

Re: MX2 Integration Marathon \int \dfrac{x^4}{x^3-1}\mathop{\mathrm{d}x}

Re: HSC 2013 3U Marathon Thread $Use calculus to sketch the curve $ y = \frac{\ln x}{x} $ and find the maximum function value. Use this to deduce that if $ e\le a<b $ then $ b^a<a^b $ so that in particular, $\\ \pi^e<e^\pi.

Do all HSC past papers. Note down topics for past HSCs - see if there is a trend in popular topics for the harder questions. With 3U, if you are a 4U student, concentrate on minimising mistakes and accuracy. For a 2/3U student, concentrate on mastering all the concepts well and consolidating...

Re: HSC 2013 4U Marathon $Harder 3U $ \subset $ 4U.$

Lol is that serious use of a reason or..

Did you switch from USYD to unsw?

Since when we're you a bearded southern cow boy? Learn something new erryday.

Excuse me? I'm a minion?

Economics is a social science. It is the study of human behaviour.

What is the quadratic equation whose roots are the intersections of x^2 + y^2 = 4 and 4x + 3y - 10 = 0? What properties of this quadratic tell you if the line is a tangent to the circle? Expand the right hand side.
