well the first two are very easy: for lnf(x) you draw in y=1. now when f(x)<0 lnf(x) is undefined so you get rid of it. f(x)=0 lnf(x) is still undefined so you put in vertical asymptotes. Next where y=1 intersects f(x) lnf(x) becomes 0. For 0<f(x)<1 lnf(x) <0 and for f(x)>1 lnf(x) >0. Now you...

The general harder 3 unit unequalities Are one of the easier parts of harder 3u after circle geo and induction

I believe it is very beneficial to Know the 3unit course for 4u. I did The 3u HSC in year 11 and in year 12 It made 4u easier for me

A good method is the Greek one, start from 8 and work backwards, for some reason It works faster

its a 3hr test, i still have over an hour to check it with that 20 min break

How I do a 4unit paper: Q1 integration 5-8 Q2 complex 5-8 Q3 5-10 mins depends on length Q4 5 6 same as 3 Q 7 8 8-20 mins depending on difficulty Test done in 56-86 mins. Next take a 20 minute break/nap Your hand will need it

Re: 2012 HSC MX2 Marathon oh poor carrot, so long lol.... Here is the shorter way:

No usyd is the slowest

Is the question to implicitly differentiate It cause there is no dy/dx in the supposed Answer

I'm on iPhone, but all you is equate the two. Then you take one of th polynomials to the other Side and them you factorise the like powers and then You state this can only equal zero only if the coefs of Each equals zero and you get the reunified answe

Re: 2012 HSC MX2 Marathon nooblet what are you trying to imply here?

So the while discrete component for 6 weeks is just on the first two topics I listed ? No set theory?

Re: 2012 HSC MX1 Marathon Someth1ng you are completely and 200% right, extension 2 isn't fun at all English is just a terrible subject in general, all levels not just ext 2

for people who did 4u maths and were decent at it will find normal maths a joke, i know of someone who did not go to one lecture or one tute, only studied the night before each quiz and test and got a credit in norm maths.

Re: 2012 HSC MX1 Marathon do you mean prove the ap sum formula for that particular series?

yay carrot approves of my shitty paint diagrams

correct

sorry in advance carrot
