Jeremy the inverse thing was y=e^X-1 i think. Ive stuffed the limit question, probability, binomial and induction but everything else i got answers for and should get marks for the ones i didn't get. I'm done now it's all over!

i rekon i got 76\84 if i dun make any stupid mistakes:(
didn't have time to finish the last question on binomial theorem cuz i took my time in the first 6 questions
and i forgot to do a 2 mark question, just left it out and didn't go back to it lol

for that induction q. u need to use sum of AP, S_n=n\2(a+l) to get rid of the "dots"...

If I didn't make any stupid mistakes I should get 73/84l I couldn't get neither the binomial or induction questions (it would have helped if I had done the binomial exercise, and revised induction since year 11 I spose :p). Couldn't do the first part of the cone question either, apart from that it was all kosher :rolleyes:

It was a good paper!
I don't think I did too bad!
We had the last Binomial Question cancelled - rest was same!

People - just one question:
For the Motion in a straight line, when it asked for sets of values for x, was it
x<- sqrt 10 and x> sqrt 10
Because that's what i got...and it looked a bit dodgy...

NO MORE MATH!!! :D:D
(till the hsc:D)

the cone one u need to use tan 45=radius\1
so radius=1
the smaller radius is =1-h
den u do volume of that thing =total volume minus volume up da top part
den get V=pi\3 [1-(1-h)³] and expanding it yields the required expression;)

Why?
It was a parabola - those values would be below the x-axis...how can you have that?

damn.. hopefully i still get some marks then.. beause i just didnt minus the volume of the top part so i couldnt get my answer... damn

rofl i had r=h-1 written on my page... fucksake

when h=0.5, i got something around pi/40 which is probably wrong :(
pi/40? Now this is scaring me.
