Re: HSC 2013 4U Marathon Err...

Bands like August Burns Red, Parkway Drive, In Flames etc.

Lead guitarist for a reasonably successful metal band probably.

Analysis will never happen in high school, it is too sophisticated a topic to be part of MX2 and by a pretty large margin. Linear algebra makes more sense, at least the basics thereof. Personally I would remove Graphs and Conics from the course and replace them with two topics out of...

Re: HSC 2013 4U Marathon For the UNSW problem, one would have to prove that f is differentiable before one could differentiate it! Also I don't quite get your reasoning for this question Sy, why must iterations of f applied to an arbitrary a converge, and why must this limit be in the range of...

Re: HSC 2013 4U Marathon You don't need to know the name of such functions or any properties thereof to answer this question.

Re: HSC 2013 4U Marathon Some random calculus true/false practice for multiple choice: 1. Every continuous function is differentiable. 2. Every differentiable function is continuous. 3. Every differentiable function has a continuous derivative. 4. If a differentiable f attains a maximum at...

Re: HSC 2013 4U Marathon $Find (with proof) all functions $f$ defined on the real line such that:\\ $|f(x)-f(y)|\leq (x-y)^2$ for all real $x$ and $y$. $

Fair enough, valid points. Just wanted to put my thoughts out there, hopefully they are of some help to someone out there.

The thing is I don't think this is really a valid argument unless you are aiming for things like the mid 99s for your university course (or for personal reasons). Std makes it near impossible to hit B6 but everything else is achievable, and high 80s in every subject (and higher in the subjects...

Re: The p00n thread Well, thats precisely what I'm objecting to...I wish this wasn't the case for most people.

Re: The p00n thread Beg to differ. I was told I was more than capable of doing adv but I chose standard as I simply didn't enjoy english and it required far less effort to prepare for. I couldn't have gotten a much better mark with advanced, and I would have had to work a lot harder to get the...

Re: The p00n thread Well with a trade-off in difficulty. The system is designed so that an equal amount of effort in any two units (for which you are equally talented) should get you roughly equal results. I just say this because it often makes sense to do an easier version of a subject if you...

Re: The p00n thread Out of interest, for what reason do you think she shouldn't do standard?

Yep.

Yeah, a random z coordinate and a random line of longitude would do. Yeah a light source was perhaps a poor choice to explain, the projection is perpendicular to the line joining the N and S poles.

Such a construction has been known since Archimedes. Imagine that you have a transparent sphere with an internal linear light source joining the north and south poles. Wrap this sphere in a cyclinder whose axis of symmetry contains this light source. Now the "projection" from points on the...

Yeah man, am in love with these things. Amps max out their potential but they are still pretty amazing from standard sources.

Look for a solution of the form ax^p where a and p are two real constants to be determined. It is easy from here.

Re: HSC 2013 4U Marathon Yes but the existence and uniqueness of a MINIMAL polynomial is not immediately clear and must be proven. And thanks :).
