ye, but these guys who've gottan 1/8
mustve found dr/dt, and multiplyied it by 2Pi to get rate c is changing

Which seems to be valid to me.

*shrugs*
hopefully both methods are marked correct

Just worked it out:
f(a+b) = f(a) + f(b)

show that f(0)=1

let a (or b) =0

therefore, if a=0, f(0+b) = f(0) + f(b)
f(b) = f(0) + f(b)
Hence f(0) =1

Y couldnt i have worked that out that in the exam...hmmmmmm.

Still dun know the second part of that question though.

 

[-=«MÄLÅÇhïtÊ»=-]

" therefore, if a=0, f(0+b) = f(0) + f(b)
f(b) = f(0) + f(b)
Hence f(0) =1 "

dood, if f(b) = f(0) + f(b)
then f(0) = 0


what was the question again?
my memory's fading...i dumped all my maths knowledge to give room for other subjects

wasnt it f(a+b) = f(a)f(b) ?
or was it f(a+b) = f(a) + f(b)

Coz if it was f(a+b) = f(a)f(b)
im not sure if this is correct, coz i fink the ques said sumfin about real numbers, >1 or sumfin so i didn't use 0

but if u use 0, then:

f(0+b) = f(0)(b)
f(0+b)=f(b)
therefore, f(0) = 1

But i cant remember ques

try and feel some kind of sympathy for the rest of those who didn't do as well as you, instead of telling us that you're upset cos u didn't get into the 90s.

Well, i screwed my trial hard.

i got the results back already, my teacher is pretty good about marking quickly and i only got 39%

so its fucked bad, it was harder than last years trial imo i did last years and got alot of it out but when i went into my trials i was like wtf???

but after the exam some of the questions seemed so easy when i thought about it.

i just hope the hsc isnt like that

oh shit man...39%....for my half yearlys i got 47%.....im so scaredon getting this one back...

 

[mkogan]

my friends got 93%!!!!!
i'm so hoping i can also get in the 90's!!!!!

 

[EXA BOY]

shut thew fk up with the 90's calls damitt i think we do independant whic my 3U is on tues and i9m screwed 4 it, will b cheering 2 pass!!!!

 

[Dude]

The f(a) , f(b) wasn't impossible. All you have to do is look at the information and fit the pieces of the puzzle together. It was a question of logic.

f(a + b) = f(a) * f(b)

therefore

f(0 + x) = f(0)*f(x)
f(x) = F(0) * f(x)
divide by f(x), then
f(0) = 1
All you do is place a zero in and the rest of the answer is damn easy. Look at what they ask you and look at the function and sub in anything you know!!

yeh that was catholic trials...past hsc papers were easier i reckon

 

[Mistress Lilith]

Simply put the test was: OMG (what I remember of it anyway)

I didn't think it was possible to make up stuff for maths--but I made up quite alot of bs trying to make something equal to something else (which was wrong but oh well) lol

 

[Doylie]

oh bugger me, i get my result back tomorrow and if i get over 50% ill be cheering, if i get over 60% i'll be stunned...
Stupid CSSA...
Oi, is it true that the CSSA trials are harder than the actual HSC exams?? i freakin hope so..

 

[Morgues]

I think the HSC is harder.......thing is you have a lot more time to study for the HSC compared to trials

I got 73%.......my highest mark for the year in ext 1

 

[Sazzy]

I'm getting my results tomorrow! Eeek...
Hey Malachite, i'm sorry for my nasty comment. It was mean. I was just upset at myself for not doing as well.
