What? No one wants Portal 2? It is teh Hax0r

How does the BoS take merge this information? I have heard of two theories. 1) The BoS takes your rank at school. Then they look at a person from your school who got that rank in the externals. Then they give you the mark that person got. 2) The BoS takes your school marks and modulates them...

Hello, I'm quite interested in this course, doing 4U maths at school. What is the kind of difficulty in this course compared with other courses, e.g. finance. Which are the best universities for doing this? I heard Maq is the best, but UNSW if you can get a co-op program. What about ANU or...

What are a few causes for our persistent and large CAD? (I know this is in topic three my school's social science faculty is weird)

Thanks! I just needed a method to start.

If P(x)=x^6+x^4+x^2+1 show that the solutions of P(x)=0 are among the solutions of the equation x^8-1=0. Hence factorize P(x) over R and The equation x^n +px - q = 0 has a double root show that (p/n)^n + (q/(n-1))^n-1 = 0 Thank you!

Two circles touch internally at A. The tangent at P on the smaller circle cuts the larger circle at Q and R. Prove that AP bisects (Angle)RAQ. Thanks in advance. Edit: This question is question 28 on page 18 of New Senior Mathematics, 3U by Fitzpatrick

Anyone used Sharpie Pen? It's a bit expensive, $6 for two, but it's great, a felt tip that's not too inky when you write slow, but not too dry when you write fast. Apparently I'm the only one who thinks their good though o.O

Here's a tip, if you have an intuition feel about a question, go with it, even if that means drawing a line here or there.

Usually the texts books will have it all. For example, Fitzpatrick's New Senior Mathematics, three unit course has it after the introduction. You will also need to know how to apply the rules, so doing some examples would be quite beneficial. Good Luck.

How about you have a two table format in Microsoft Word. Have the syllabus dot points on one side of the table and your notes, in dot points, on the other side. This way you'll only maybe 10 pages. I have a set of chemistry notes that are like 7 pages per topic, cause my memory sucks.

Hey I'm going to my half yearlies on monday, starting with English Area of Study and Module A, what advice would you give me? Sleep early? Drink a ton of Red Bull?

We know how many moles of SO2 are there as at 25 deg and 100kPa there are 24.79L/Mole N(SO2)=2.48/24.79 =0.1 moles Since it is dissolved in 1L of water, the concentration is 0.1 mole/L We can write an equation for SO2 reacting with water SO2+H2O->H2SO3 and an equation for the...

How about this one, Prove (1+cos(x) +isin(x))^{n} = (2^{n}cos\frac{x}{2}(cos\frac{nx}{2}+isin\frac{nx}{2})) P.S. How can I use LaTex?

Anyone up for tackling Q2? Thanks

If w is a cube root of unity then, by definition, w^3=1 and w^2+w+1=0 If w is a root of P(x) then P(w)=0 L.H.S =3(w^2)(w^3) + 2w(w^3) + w^3 - 6w^2 - 5w - 4 =3w^2 + 2w + 1 - 6w^2 - 5w - 4 (since w^3=1) =-3w^2 - 3w - 3 =-3(w^2 + w +1) =-3(o) =0 =R.H.S Q.E.D

Thanks for the add! Are you doing accelerated maths?

Where did you pull the arg(ab) in L.H.S from?

Hi, I have 2 questions regarding complex numbers, 1. Is this algebraic identity true? If so, could you prove it? arg(a*b)=arg(a) + arg(b) 2.Let H and K be the points representing the roots of x^2+2px+q where p,q are real and p^2(is less than)q. Find the algebraic relation satisfied by p and q...

Wow this is really great. Thanks for uploading this!
