CSSA advanced mathematics- dude wtf?! (2 Viewers)

Yes, actually. Is reading over a paper too much to ask these days?

They prob do, but not enough. Its only trials so they prob like ah its alright. 3 checks is enough. Whereas the HSC would prob be checked by 20 different people 40 different times.

anyone else fuck up changing degrees to radians with that simpson rule q?

Nah man i tested the last box value and it was in radians so i knew i had to use radians XDDD

I can corroborate this!

It was absolute value so | x-a | < or equal to b
The rule is that -b < |x-a| < b
so if b = 3 and a = 9
its -3 < x-9 < 3 -- (now plus 9)
6 <(or equal) x <(or equal) 12 (from the line given u can see that)

Now iono if thats right... but q10 of the paper i didn't even bother with probability. x_x

hahahaha we haven't even done probability yet, so our question was changed to some displacement, velocity acceleration question... and NO ONE answered the question.
there's 12 marks gone down the drain!

are you dumb, applications of calculus is the easiest and most fun topic of maths, you guys all fail, should have got a tutor lolololool

 

[MrBrightside]

What did you guys do for that university scholarship question?

Was it annuities or loan repayments?

I got stuck on the An part because I initially thought it was loan repayments, then decided it was annuities, but now I think it was loan repayments. (luckily I only put one line through it, so I might be able to get a mark or 2 for it).

LOL after reading this entire thread I'm a bit worried now ._. Although I have made out bits i should revise so i guess thats a bit of an advantage to my side. MUST DO WELL.

 

[krnofdrg]

i probably did the worst in the state... i'd get around 30/100 and its all my fault for not revising properly =.=

same!!!
i substituted what they gave us in both radian and degree mode then worked out it was in radian, then solved. hopefully there were no silly mistakes!

ummm...
are you kidding me.
