As most of you are aware, the 2005 CSSA trial is tomorrow (Monday). Considering the other thread was about asking what marks in the exam would get a band 6, I decided to start up a thread dedicated to the actual exam. Keep all comments about the exam in here please. Most importantly good luck...

Haha did you expect a different equation for the volume of a pyramid?

What I meant is that I dont think the 2004 ext 1 exam is a good indication of the difficulty of the ext 1 CSSA trials, since I normally wouldnt have gotten 83/84 for other years.

Not to sound arrogant, but I dont think the 2004 CSSA ext1 exam was too difficult. I got 83/84 and I didnt even do 4 unit maths.

If you want the step by step proof:

The Wilson Cloud Chamber contains alcohol vapour from methylated spirits inside a petri dish. Ice is used to cool it to very low temperatures. When alpha and beta particles are emitted from a radioactive source inside the chamber, they ionise air molecules and the alcohol condenses around the...

Who knows, its a mystery only known to the Board. Last year I'd say they were about even but most people generally tend to think CSSA is harder

If its something like a polynomial then you can be guaranteed its continuous. If its a rational algebraic function (ie. polynomial divided by polynomial) its guaranteed to be continuous everywhere except where the denominator is 0 (eg. Slide Rule's 1/x function). Continuity is preserved through...

If you get asked to integrate ln(x) in an exam you can complain that its beyond the scope. More so for ln(ln(x)).

(@ + sin2@)/3@ = (@/3@) + (sin2@/3@) = 1/3 + 2/3*(sin2@/2@) taking the limit gives 1 edit: copied the question wrong. Corrected

maybe they're being realistic?

As x approaches really large negative numbers, ex approaches 0, thus leaving the equation as 1/(1+0), ie theres an asymptote at y = 1.

Haha so did like everyone else that sat it :p

It was great for me too. I got a participation :D

PDF version including FF's answers for the questions he did.

It could just be the program i used with word to do the maths parts. Ill convert to pdf so its more accessible.

If you dont know what integration and differentiation are then perhaps your problem doesnt lie in not being able to read lengthy questions.

So obviously, you are not using maths in any way in your life are you? *cough*computer*cough*

Like I said, i did them quickly in between classes. Where exactly are there errors?
