what did people get for that inverse thingy like the f-1(x) ?
just want to see if what i did was right i rushed it

 

[laurel18]

i think the inverse was: y=e^(x-1)

 

[fantasy27]

i think the inverse was: y=e^(x-1)

yeaps.. i got that too..

 

[Boz_87]

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!

 

[FinalFantasy]

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"...

 

[Boz_87]

Damn it was an AP! Thats 2 unit stuff. Wat did pplz get for the rates of change question?

 

[Kutay]

boz.... yeh i screwed it lol anyhow if i pass i will be happy anyhow 1 more exam to go

 

[laurel18]

lol...obviously I need more induction revision haha

 

[Kutay]

what mark u estimating

 

[laurel18]

boz.... yeh i screwed it lol anyhow if i pass i will be happy anyhow 1 more exam to go

don't worry...many people at my school thought it was hard...so you're not alone...Good luck for your other exam mate

 

[laurel18]

hmm...i'll be happy to pass or get 60ish

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 ). Couldn't do the first part of the cone question either, apart from that it was all kosher

i couldn't get the first part either.. hopefully i got the second part right.. i tried and i tried for the first part.. i got something similar.. but it wasnt it! =.="""

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!!!
(till the hsc)

 

[FinalFantasy]

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

if i remember correctly i got -root10<=x<=root10

 

[ishq]

if i remember correctly i got -root10<=x<=root10

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

if i remember correctly i got -root10<=x<=root10

how do u get the < and > signs? im a bit confused, i left my answer with ='s

uh oh!

 

[ishq]

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.

i dunno
maybe i remembered incorrectly
