I'm not saying its right or wrong - but look at what you're arguing. You want bos to tell jrahs to stop teaching their students ahead of time, stick with what the syllabus says. That is the biggest tragedy that can happen. These students talents need to be nurtured not halted.

Oh noes! People are learning things ahead of what bos says they should! If they have the ability to do that work in year 9, then who are the teachers to stop them from doing it? I'd say the majority of ruse'rs would probably know that stuff before they even set foot in the maths classroom anyways.

Wow, what a creative way to say 'Good Luck' :p Good luck all!

"c) Acmilan has at least one assignment due friday" Electrical engineering exam wednesday IT major due thursday Computer science exam friday However im off tomorrow so if someone hasnt dont it already i might give it a go.

Sometimes second derivative is impractical, especially when the first derivative is so massive that the 2nd one will be even more massive, and thus making it difficult to prove if it will be positive or negative if all you have to go by is a letter. I suggest if you do test using first...

http://community.boredofstudies.org/attachment.php?attachmentid=10260 Those were ones i typed up quickly, most would be right but theres likely to be some mistakes.

which trial?

The function goes towards infinity, half of infinity is still infinity. So the 1/2 makes no difference on the amplitude, it just makes the graph look a little more fatter.

According to this, the K means you are working with some constants in the calculations. Thats as far as i can gather from that, I'm not too familiar with that calculator.

For a > b, f(a) > f(b)

The gradient is always positive, doesnt have to always increase though.

I did a short C code and, unless i made an error, it seems to diverge. So maybe you just need to prove it diverges Edit: no it doesnt, my mistake, it seems to converge to 3. #include < stdio.h> int main() { float sum = 0, i = 0, u_n = 1.0/3.0; for (i; i < 10; i++) {...

word.'s one would be most appropriate. When in doubt, create your own functions :) Eg. y = x3/ex for x >= 0 and y = x3ex for x < 0

12.3 The functions y = ax and y = logax for a > 0 and real x. Change of base. 12.4 The derivatives of y = ax and y = logax. Natural logarithms and exponential function. Yes, it's in the syllabus.

I dont know, it's best to email bos themselves to ask these questions

I dont think you are allowed to use a pencil. If you could, it would say so at the front. Take the SDD exam for example, it says to draw diagrams in pencil: http://www.boardofstudies.nsw.edu.au/hsc_exams/hsc2004exams/pdf_doc/software_design_dev_04.pdf However the Maths Ext 2 says nothing...

I must commend you KFunk, you truely have the right frame of mind and attitude to be a great mathematician in the future! (if that's your thing ;)).

It's people like you that strengthen my love of maths.

Tongue speakers = pentecostals.

err yeah that 8 is iffy, i'd probably have said A.
