[3li]

wat did u guys get for this? i got 114.. im surprised cos i didnt do silly mistakes

was this a comparatively easy test? they had alot of lead-up questions, and i hope 06 will have a similar structure.

Not that I know of.

Are you serious you got 114?!

The 2003 paper isn't very hard, it's just very annoying with all the algebraic mess you have to handle. You have to be very careful in your working with this paper. In particular, the question about something to do with the irrationality of pi was a bitch to do with all the work involved and even my tutor gave up when he realised he didn't get the result he was supposed to prove due to a small mistake somewhere in the beginning of his working...lol

I put up solutions for the 2003 paper at

There is an alternative way to prove irrationality of pi at the end of the file

theres a faster way to prove irrationality of pie, we learnt it in yr 10... its also contradiction but much faster

 

[buchanan]

You can also do it with continued fractions.

114, thats not bad, should get you a 95ish.

As a raw mark you mean? That'll be 98-99 aligned for sure....

 

[Wackedupwacko]

thats 99 possibly 100 aligned depending on how many freaks get marks similar or higher.... for that paper i got about 97.... too many stupid errors

 

[3li]

now that theyve asked pie and e
what other irrationality proof culd they ask for this year, thats within our realm

i am so screwed......

 

[housemouse]

I dont even know what you guys are talking about.

Which question is this in the 03 paper?

something like.. hmm sin(pi/7) is not rational perhaps
