Fuck, now you've made me think of it that way lol.

It's your choice, but a couple weeks with less exercise than usual won't have much of an impact and you wont lose muscle, rather you will just plateau. The HSC is pretty important, so I'd advise for the next couple of weeks, study more, exercise less, and then after the HSC everything can go...

Haha last year my teacher let me throw a cream pie at his face for reciting 100 digits of pi. Now I only now around 10.

You can do indefinite integral's first, so definite integral's will be a bit easier.

Yeah it's almost the same as it was before, so it's still very hard to decide what to drop. If you really want to do 4U, I think dropping a subject is the only option, 14 units is very hard.

I'm so glad I won't have to do this, the only writing subject I have is English.

It doesn't really matter if it's asking for the anti-derivative or the indefinite integral with a integral sign, it's the exact same thing.

Year 11 maths is way better than any of the maths in 7-10.

I'm not an atar estimator, but I know it can be difficult to estimate people like you, really high ranks in low schools. It pretty much depends all on you're externals though.

It's cool we all make mistakes.

I think people are confused because you said the integral of 2/x is ln(x), when it should be 2ln(x).

The gradient of a line is equal to the gradient it makes with the x-axis in the positive direction. This is because tan(x) is opposite over adjacent, which is rise over run, so tan(x) is the gradient. In this case, the angle with the x-axis is not in the positive direction, so we make the...

If something is proportional to something else, say a to b, then a/b is a constant. I find this question a little hard to explain thoroughly, so I'll leave that for someone else to do, but I'll do an example. Let's take the function y=2^x. We can use implicit differentiation to find the...

Just to add something, I wanna say calculating the logarithms on the calculator wont work for instances like ii), where the value is actually 2.01 but the answer will be 2.02 as that is the method the markers want you to use.

I thought probability was Year 12 2U?

9. a) i) There are 2 awards being given out and ten students to give it to. So there are 10 possibilities to give the first award, and though the same person can get both awards there are another 10 possibilities to give out the second award, so the total number of possibilities is 10x10=100 a)...

I'm using Cambridge, this is in 6D and Induction is at the end at 6N, so the method they want isn't induction. Induction probably would be the best way to prove it though I haven't learnt it yet.

Just cause you're accelerating maths doesn't mean that you're good at everything, I personally don't know how to English at all.

Hey BoS, I would like to know how to show that a sequence follows a certain rule, is all you do substitute in values for n and show that for the first couple of values of n it is true, or do you have to rigorously prove the sequence. My question is with c), http://m.imgur.com/1uqEY6t I feel...
