Re: HSC 2013 2U Marathon Simplify: (x-a)(x-b)(x-c)...(x-y)(x-z)

Re: HSC 2013 2U Marathon Don't take x=-3 otherwise \ln(f(x)) < 0 :)

Re: HSC 2013 2U Marathon 3x^2 = 6 -7x Solve quadratic.

Re: HSC 2013 2U Marathon Jigsaw and Detective Hoffman play a game. There are two blank dice with 6 sides each. Jigsaw has to fill in each side of both dice with a number between 1 and 12, and all numbers must be used. So each number must appear, and can only appear, once (i.e. if you have a 3...

awwwwww That's so much cuter than mine.

I'm going to be using Jacaranda for physics in year 12, it seems pretty good. Sorry but I don't do biology or chemistry so can't say anything about them.

If you know probability, here is a question I posted in the year 11 marathon. a) Let S(n) = 1 + 2 + 3 + ... + n This is S(n) expressed in ascending order. By considering S(n) in descending order show that S(n) = \frac{1}{2}n(n+1) b) Consider a bag. This bag has every single letter of the...

You could make the observation that the area of the white outer is equal to the area of the white inner.

Oh I really hope you're right, otherwise I might have to reconsider my aims and goals.

It's scary that I'm going to have to compete with people like you in the HSC .

You could try acquiring some 2012 2U trials? Other than that I'm not aware of many (if any) m/c practice resources.

lol I forgot to answer the actual question. No, I don't personally make notes, but some of my close friends do and it really benefits them. So I'd recommend finding what you like best and sticking with that.

But year 11 is over, year 12 starts in just over a week from now!

Oh, thanks for the heads up. I'm still on my L's, so yeah...

omg you guys are so smart :( I've started complex numbers these holidays, but I've got no idea about some of the stuff in this thread.

Yep just always go by what the book says.

I only did 12 units in prelim, need to work out what to drop though after picking up maths/english :S

L'Hopital's rule is taught in 1st year uni maths, but can be used when evaluating certain limits. Hence why people talk about it a lot :)

You can't use stuff like L'Hopital's rule in the HSC, so they can punish you.

There isn't even a standard integral to integrate logs.
