Do you understand the idea behind annuities? Because then memorising wouldn't be necessary. Perhaps a cashflow diagram would help... Given that it's general maths I don't think they would ask too hard questions involving annuities...

The difficulty of exams depends on who the lecturer is. Newbury (head of school) sets ridiculously easy exams, whilst Joe Wolfe sets quite challenging questions.

I do wonder though, if that is a scaled passed or a raw pass. Because I think that in the past the raw failure rate was something like 50-70%, depending on who the lecturer was.

Exam Results by Elizabeth Angstmann - Friday, 29 June 2012, 11:49 AM You can now check if you have passed the exam. If you go to the grades tab (in moodle) on the left at the bottom of the list there is a section "Final Exam" this has either a 0 or a 1 (binary) in it. If it is 1 you have...

I had Wildberger as a tutor for several variable calculus... he was alright at what he did. Wouldn't say the best... but he marked tests leniently, which was nice.

d/dx e^f(x) = f'(x) e^f(x) So integral f'(x) e^f(x) dx = e^f(x) + c So you recognise the "pattern" in 2U.

If I recall correctly, most metals have a valence of 2+...

It's been a while since HSC Chem, but don't you use the periodic table? :\

I think he means that if get t=13.35 years and the question asks "In which year does it occur?" then the answer is that it occurs in the 14th year (since t=13.35 is in the 14th year).

That's because it's really easy to get 100 in those courses if you're half decent at maths (they ask pretty standard/tutorial-like questions in the final examinations for the lower level maths). I did a 'non capped' version of MATH2520 (for reasons that I cbb explaining here) and got 100...

Re: 2012 HSC MX2 Marathon use the sub. x=rtan theta...

The questions are alright for volumes and conics, especially if your school uses CSSA trials. But I heard that they're getting scrapped anyway in favour of Bill Pender.

If you go to UNSW you shouldn't buy the prescribed textbooks for 1st year maths (they even say in the lectures that it's not necessary, but according to the bookshop it is necessary).

Re: 2012 HSC MX2 Marathon Prove analytic continuation. It actually is a VERY difficult theorem to prove.

Most schools get their half yearly questions from (very old) past HSC papers and/or CSSA trials. So it may be good having a looking at them...

Re: 2012 HSC MX2 Marathon Indeed the integral doesn't converge absolutely. What everyone else wrote is the Cauchy Principal Value. This assigns a value to such integrals. But of course that was not asked here.

Re: 2012 HSC MX2 Marathon Haha nice. What mark did you end up getting for MX2?

I still think Trebla >> Pokka...

Haha, yeah it was meant to be trivial. In my year the "smart" people took ages to do it, whereas the "dumb" people took like 2 minutes to figure it out... lol

Here is a variation of that problem. 1=5 2=17 3=9 4=21 5=? Find '?'.
