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
Originally posted by 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...
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.
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
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
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.....
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.
