People should consult their teachers at school

My firm opinion is that using these programs are no better than traditional textbooks because the interaction is limited... so it is basically just like a talking textbook... Also had a look at the maths power website, it gives the same vibes as self help books. here are some examples: "It is...

It directly affects your UAI fool. Unless maths doesn't count for you or in the other unlikely case where you and your classmate performs equally well in the HSC

If anyone cares, for general n. (D is the set of divisors of n greater than 2. The first formlua applies if n is even, the second when n is odd)

Doing things in order is usually the way to go, there are good reasons for that 1) Difficulty generally increases with question number. 2) Less attention devoted to keeping track of parts not completed.

You should think of induction as proving something by dividing the statement into cases: (first case, second case, third case, fourth case, so on). So here, it will be natural to set this to the number of sides: ie 'n' in your induction is the number of sides of the polygons. So first you...

My other self says that yes it's very bad manners and it's compounded by the fact that you're giving him notice this late

Since you don't like him (so presumably will not be interacting with him), there shouldn't be any practical problems, unless being seen as capricious becomes a problem for you. Ofcourse, he will feel betrayed...

Are you sure it's not |x|^3 + |y|^3 = a^3 ?

the argand plane is just there for you to visualise and gain insight, doesn't remove the need to blast through the algebra

to determine the sign you expand and check.. after a few hundred times it will be obvious by the way it's a^3 + b^3 = (a + b)(a^2 - ab + b^2)

do as many(subjects) as you can in year 11 .. doesn't hurt my grammar is becoming worse by the day..

Don't know about your boy, but if I am depressed and someone comes up to talk to me ... I will get VERY annoyed...

You need to lodge some appeals... you always want the first position..

Most people don't do well coz they are too tied up with "concepts" but can't even perform a simple algrebraic simplication or a simple integration

Let's be friends

suck it up, that's how things are meant to work

If you thought about this earlier you could have accelerated your HSC and go to uni with him. Well... if he lives close enough you can still see him quite often...a relationship doesn't entail daily 6 hour companionship

all you need is a permutation group G (here, rotation) and a G-set X (here, the different arrangements, where each spot on the circle is considered distinct) an elementary application: how many ways can you arrange 12 people in a circle? Rotation of 0 degrees: all 12! configurations are...

80 should be the answer, you don't need brute force for this... think burnside+frobenius+cauchy EDIT: I mistakenly place 157 there.. It's 80 Here's how you do it: You consider the spots aroud the circle as distinct, and look at how it behaves under rotations Burnside's lemma states that the...
