yes i got pi/4 aswell for it

the last smh was "how long does it take to return to 0"

gave it a minute to sink..still didnt c so i moved on..

i used the last 5 mins i had spare to look @ it..tried couple of things but didnt get it...bah =(

Well Vietz is rite bout one thing.... comparin it 2 the last 3 years, that was easy!

But time was my enemy and half of Q7. I expected a killer but it wasnt as hard as doin freakin simpsons and volume (its easy now but b4 i was stumped)

BUT THE EXAM WASNT EASY!

Also the sphere question was easy!


Also Vietz do i know u from somewhere???? U aint that Korean guy from my skool are u?

Doylie, if u do 4u. Why r u looking forward to the 2u test? 4u ppl dont do 2u....

 

[Viceroy]

the one where u had to change the limits and then when u did u got a plus-minus infront of one caues u had to square root them

 

[Morgues]

What did people get for the sphere one?

seems like my school edited the paper rather heavily as half the questions mentioned weren't in my test

 

[chanfky]

for that sphere, you find the rate of change of the circumference right??
i think i got 1/?.. 1/8? 1/18?
can't remember exactly...

 

[Viceroy]

i fucked it up also but its probably cause i was getting all the maths shit back in my head as for the last week ive been thinking religion and english

 

[Dumbarse]

yeh the test was hard, too in depth, too many questions, not enough time.... i probably aced it but

 

[-=«MÄLÅÇhïtÊ»=-]

i got 3/8 for the sphere ques...
but ino lotta ppl who got 1/8

weird..
hope im not wrong


i let circumference = c
so change in equator is dc/dt

uno dv/dt = 25

and i worked out dc/dv = 3/200

25 x 3/200 = 3/8

*shrugs*

u guys used volume of sphere = 4/3(Pi)r^3 right?
coz if u did v=4(Pi)r^3, then u'd get 1/8

 

[mkogan]

OMg, hardest trial ever!!!

Although i did all the questions, i could not do 3a) i) damn that triangle to hell.

hope the 4 unit is gona be better!!!!

YESSSSSSSSSSSSSSSSSSSSSSss

I love u!!!!

Eat Shit Malakite.... IT WAS 1/8..... u gave me a scare 4 a while!

 

[chanfky]

So I am right???

Oh well, I'll just assume I'm right for the time being.

 

[Doylie]

Oops my bad malachite, i meant to say i do 3 unit..

 

[Ozz^E]

I thought it was pretty okay considering wat CSSA trialz are normally like. I hate 3a), took me like 10 mins..but i got it in the end. I just fund out that i FULLY stuffed up in the sphere question..it used the equator as the diameter..(dumb me).
And then the last SHM quetsion asking for time taken to get to O..im bloody trying t formulaes when it was a simple trig eq. Other then that, 7ai) was tricky but i amnged the induction and iii and b was pretty doable but a silly mistake meant i lose at least 3 of the 6 marks.

Overall it hought i was pretty good.

Ha ha you smart people....
the 3U exam was not THAT great... question 1 was mad however hehehe... the projectile question was somewhat confusing...
speaking of which, the guy that said that they havent done the topic of calculus... thats a major topic to learn b4 the HSC

 

[Dumbarse]

u idiots, the last SHM question u just had to sub in x=0 to the equation u were given, cause if u subed in time = 0 it started at x=3, the sin0 was 0 and the cos0 was one, so it was pretty easy if thats how u were supposed to do it

 

[mojo]

for the SHM it slowing down and traveling to the right?
hmmmm wat else...
i couldnt do dat projectile Quesiton seond part.... was it like when the two y's are equal?
for dat trig question i could only get up to c^2 = bd - 2ac
and how do u do the f(a+b) question??
omg hope i passed.....

 

[KilledInAction]

Do you guys get to keep the question paper for any of the Catholic Trials? I haven't done my 3u paper yet and thought it would be good practice...quite a lot of my friends do the Catholic paper and the general agreement from them was that it was hard.

 

[-=«MÄLÅÇhïtÊ»=-]

ivr had another go at the sphere ques
i think there r 2 ways of doing it.

If u find dr/dt and times it by 2Pi u get 1/8

Or if u find dc/dt (c=circimference) u get 3/8

I think both answers should b correct. The reason they're diff is coz the value of dv/dt they gave u may not be realistic.

 

[Vietz]

i would assume the equator is the circumfernce...not the radius..
