hey you guys were right , the solution was A=Pe^kt but the best thing is i had that in part 2 so they gave me the mark for it anyway.

nah, this isn't it, I know how to do that, it was in part b for like 3 marks. part a was 1 mark and it was simply write the solution to this equation.

hey people, I just did a 3 unit maths assessment. It gave you this dM/Dt = -0.02M They said to write the solution to that. I mean WTF is that supposed to mean!!?? it didn't mean to get M in terms of t because that was part b of the question.

Re: Re: Here's a thought? Thats a harsh statement. Anyway, Joeys came 4th in the GPS for the HSC. I think we got 24th overall and we got 1st in the state for Physics and Primary Industries.

The type of questions are things in the form of: y=P(e^-kx) for decay and you have to differentiate it for the rate. You know they are the type of questions where dy/dx =-ky etc. the growth is just k not -k... The only thing is with the exponential growth and decay they give you a...

Hi, I was wondering if anyone could help me out with any past assessment tests on the topic of exponential growth and decay and the calculus of inverse trig? I have an assessment next week..... Thanks James

I thought that you are welcome to use techniques above that level test (i.e. 3u techniques in a 2u test) but I thought that they design the tests so that you can't use the higher techniques so that the 3u students don't have any advantage........

to determine the maximum, find dx/dt and make it equal to zero. You'll then get a t-value. Find d2x/dt2 and sub in the t-value (it shoul be negative if it is a maximum). You can then state this t-value as the maximum. To determine when it kills germs make x>0.06. i.e. 0.3te^-1.1t>0.06 and...

Thanks alot man:D Just one thing... when were you planning on scanning them cause my exam is on tuesday....

well I've already had my chem exam... I finished soo early I went back and looked over the work 5 times and ended up adding mistakes...... But I was just wondeirng so that I have the tests for the end of years....

Hi I was wondering if anyone had any prelim tests for physics? Thanks James

HI, I was wondering if anyone had any prelim tests/exams for geo? Thanks James
