FFFUUUUUUUUUUU...I got ln{(2I/10^-12)-(I/10^-12)} and then I proceeded to bloody cross multiply. If only I had solved it properly, I would have gotten 10ln2 instead of ln2I^2... :(

So for example, If I did that Simpsons rule question and got 100% right up until the end, and made a silly calc error, would you get 2/2 or 3/3 marks?

It's a two marker, but I would personally give you 2/2 since well, you got everything right up until the end..

You got (5/3)x1699 CORRECTTTTT. You just made a calculation error..

I don't think so..you can just do the (h/3){(add end values) + 2(odd) + 4(even)} and that will give you the right answer.

That's the ticket!!

Something like this.. h=20-0/4 = 5 d=(5/3){(173+168)+2(127)+4(81+195)} =2831.67

I think I got 2800..or 2600 (?)... just do the question again.

Damn, I thought you had posted some up :(

I think you looked too much into it. Instead of evaluating the square roots, you simply subtract them and they become 0.

I didn't even draw a tree diagram..I just visualised it in my head.

Hell yeah!!

I got (1,0) radius 4 in the exam, but now I can't reproduce it.. lol Someone do itttt!

Hey, Did anyone get '9' for (ii)?

Ah, I see. So out of four marks, how many would I have received?

I'm fairly sure that I included the $1000 deposited on July 1, I actually made a note of it in my head when I was doing the question. Then I got it wrong D:

Are you talking about that ridiculous probability question? Gosh, that took me *so* long to figure out :(

Hey! This was from question 9 (b) of the 2005 CSSA Trial. 9 (b) On 1 July 2005, Nadia invested $12000 in a bank account that paid interest at a rate of 6% p.a., compounded annually. (i) How much would be in the account after the payment of interest on 1 July 2015 if no additional deposits...

I GET IT! THANKSSSSS!! Also, you may go outside now :)

So you just work out the areas which are prescribed, and then basically fill in the blanks?
