Try to exploit some symmetric properties, there's a 2 line answer for both part a and b.

sketch x^x for positive x... you would have to know where it tends to as x -> 0?

upload your recent exam and your mark.

Yeah.. who cares about what others get. Repeating a 49/50 is just... DUMB... or that person has nothing better to do.

It aligns quite well.. doesn't mean it scales well though. The HSC mark you get from board of studies may be substantially higher than your raw mark, but the scale mark that UAC use may not be.

Did you mean aligned mark? or scaled mark?

my class finished 4 topics (including graphs) by this time last year

OLDerMAN always have some odd tricks up his sleeves.. I feel so inferior

integrate [x^2 / e^(x^2)] dx? there isn't one... as in it cannot be expressed in terms of functions you know

it's around 1.5 percent per UAI point

nope.. everyone would get the average exam mark as their assessment mark in that case

In my humble opinion, it will be neccessary to top the subjects to get 100.. and to get 99.5+ you need to come top 2 in subjects with decent marks.

then there must be quite ALOT of naturally smart people around. To 04'ers The bulk of your marks is determined by you, get over the habit of crediting your teachers with your bad performance.

here's one without induction, bit sketchy though: [(x+2)(x+4)...(x+2n) + (-1^n)(x-2)(x-4)...(x-2n)]/2 =sum of the terms involving odd powers of x in the expansion of [(x+2)(x+4)...(x+2n)] this can be proved by expansion (remember the relation between sum of zeroes and coefficients) if...

Not to be arrogant but that question wasn't hard.. took me about 5 mins.. the Actuarial science students at MQ probably just couldn't be bothered to think about the question. Archman typed his answer up if you haven't noticed.. it's hidden in his other post

Pulling out of Iraq is not giving in to the terrorists, it's the correct action to take regardless of any bombings. If it happens to be the same action that would have been taken to appease the terrorists, it's mere coincidence. The war against terrorism(vague as it is) has little to do with...

I wouldn't be surprised. I learnt more from this forum than school during HSC

ND.. why didn't you take it to a 3rd year MATHS student with straight HDs? yeah I am at UNSW.. by the way, you wouldn't happen to be a very good chess player would you?

ND.. missed you, where are you now?

If a piece of metal is placed in a changing magnetic field, there will be electric currents flowing through it(eddy currents). Since the piece of metal would have close to no resistance, the currents would be quite high. I am afraid this is oversimplified though.. search the board for...
