CSSA trial extension 1 (1 Viewer)

[rayd]

I think we did the CSSA exam with a couple of questions changed. It wasn't as bad as I thought it would be (I fully expected not to pass), but I made a bunch of stupid mistakes. I'm such an idiot. Like for the EPSILON question I only put 5!

Did Question 7 for you guys have a SHM tide question? Cause I thought I answered that one awesome until afterwards I realised that I had the amplitude as 3 when it should have been 1.5 :burn:

negative the SHM one in there was stupid... it had like 2 things goin in SHM ontop of each other.. or i dunno whats goin on. it was just stupid

dang .. i didn't get to finish that SHM question, i did complete everything except the last part of that question. i got 4 times that the particles meet each other but i didn't state their direction cuz i didn't have enough time .. ugh =(

honestly that test was wayyyy harder than xpected - i did all the cssa trials from 2001 - 2006 and they were heaps easierr - i got like around 85% on those ones..but today i think im probabley at the 40% markk

i even did sum past hsc papers that were easier than that triall paper ... lets just pray that our hsc paper turns out easier than our triall - so then we can use the cliche "trials are way harder than hsc"

does any1 remember this Qs ?

looks like that, how did u guys go for this one,i couldnt do the last part...

i thought the test was so & so. Wasn't good, but I'm hoping I passed.
Skipped at least 15-20 (?) marks. Not sure, don't really want to think about it.

Also, i think its security period, so posting up questions would surely advantage a lot of other people who missed the test, and ocassionaly the school would make them do the same one (perhaps). So be careful about what you say.

Overall though, it was much much harder than the past CSSA papers, although some questions were repeated.

good luck for all doing 4u im dead

[edit] who else is doing 4u [/edit]

 

[Chinmoku03]

if that was a 3unit exam, i'd love to see what a 4unit exam is like

good luck guys

Don't remind me -.-; I'm officially screwed for 4U. I'm just gonna hope the others in my class are more screwed over. (Lol, so mean -.-; )

This exam was meh-ish. I know it's only cos I haven't studied enough that I skipped quite a couple of questions. (Stupid chem exam XO)

For the g(x) = f(x) + f^-1(x) question, just compare the two domains and use logic from there. One had x>0 and the other had x>=0, so g(x) would have a domain of x>0, since it's both graphs added together.

My school hasn't taught binomial or permutation yet, so we got an easy 3D trig question for Q7B. Apparently, the rank 1 guy in my year didn't see there was an amendment for Q7B, so he did the original binomial question and didn't completely answer it, so I guess that was a really mean question >.<;

Yeah I screwed that one up. Can't remember how far I got through it, but I don't think I got very far.

oh yeah .. this one . i think i got it out ..
i solved k = 1/10 .. did anyone else get that? =X

shouldn't the graph look like this?

OMG

 

[Vladkun]

question 2 i think..
either ur school took that part out because u havnt dun permutations...
or u completley missed a page

oh thats right yeh they prob took it out.

Either way I fucked it up and that's the end of that.

I aint gonna keep bitchin'

Im screwed for 4u as well.....

 

[smallpat]

It was a binomial from hell, no one in my class enev bothered attempting it!!

 

[Buiboi]

yeah i got k=0.1

Re: 回复: Re: CSSA trial extension 1

shouldn't the graph look like this?

WHAT THE! mine didn't look like that =X my end points where [0,1] and [1,0] =/ .. but i dno .. that graph doesn't make sense to me tho .. cuz if y = x was an asymptote, the graph(s ) shudn't be able to touch it or cross it >_<

 

[meixia]

yup so did i (i think) - k = 0.1

can any1 post the original Qs up here, i completely forgot it........

 

[Buiboi]

i had a different graph?

wasnt the minimum like the intial which was like 100 or something at t=0
so it was like 300-200e0???

 

[Buiboi]

wait am i talking about the right question?? im not aye LOL

the graph question i remember something like

swapping the (1,0)

to a (0,1) and swapping teh y=0 asymptote to a x=0 asymptote or something like that
