I thought she used Pythagoras' theorem tho o.o How does implicit work with that? Don't think so. The first conics question was something about drawing an ellipse, a hyperbola, an auxiliary circle and something else. The second one was something about P(2p, 2/p) and Q(2q, 2/q), which IIRC...

Same here. The school has a YR11 and 12 uniform, meaning that I had to buy a new set of uniform just for those 2 years -.- Interesting thing is, the sister school apparently has a common room o.o

WTF? Why is an urn there? o.O; Also, what's a lace press? >.> Your school does seem to love their YR12's XD Even have sandwiches made for you OMFG, I'm jealous O.O

I've never heard of this method before. Sounds innovative o.O The part where you had to find dy/dx was a nuisance. Took me forever to differentiate the inverse tan -.-;

OMFG, I can't believe I forgot my engo teacher O.O; "This exam is out of 25, but I think you can get 2 bonus marks in it if you include certain information. So you can get 102% as a mark from me."

Can't exactly remember, but it was something like assuming (_+cos x)(_+cos y) = 3, show that cos y = _ and sin y = _, where _ means I don't remember what went there XD But to solve it, you can rearrange (_+cos x)(_+cos y) = 3 to find cos y. Once you've done that, change all cos' to sin's by...

Lol, don't complain. At least you guys have a common room XP

Lol, so much hostility against Eng in here XD Yeah, Eng's my least fav subject ATM. It's not so much the entire course that I suck at, just anything Shakespeare. Dammit, can't people see that I don't want to know what Shakespeare was implying by making a play? -.-; XD I went to this tuition...

Lol, same here. 3U's like the only subject I'm relatively confident in. But even the 3U trial, I didn't go that good. Gah, stupid inefficient time management during the holis... Should've studied more -.-; Lol, just read the previous few posts. I like hyperventilated when I saw the exam x.x;

Same here x.x; Q2 was the only part I went relatively well in, IMO. All integrations XD Altho I didn't get the volume question in Q6 (?) out x.x; Gah, was so close. Got stuck after I made the sub u = 2 - x. Forgot about being able to split the integral apart when it's from a to -a -.-;

O.O *Faints at the number 110/120 I'd be very happy if I can keep my rank with a mark of approx 60~70% or so. I skipped a lot of questions x.x;

Oh dear god, I didn't even look at the question. Just remembered that for my class, the exam was basically cut in half. We haven't covered harder 3U stuff, nor polynomials, so we didn't need to do 1 part of Q5, 1 part of Q6, 1 part of Q7 and all of Q8 <.<;

Lol, no choice? IIRC, either my school's chem teachers all only know shipwrecks, or my school doesn't have resources for other options, so we're stuck doing shipwrecks either way. Apparently, it's an easy option o.O I'm neutral towards it ATM cos school hasn't started

I spose you mean me. What you did sounds like it's similar to what I did, so I hope you're right, for the both of us ^.^; Some multiple choice questions I found difficult: Q6, the one about inducing 8 microamps in a coil. Does anyone know the right formula to use for this? I tried both emf...

Lots and lots of past papers <.<; As for today, how did everyone go? I wanna get run over by a truck cos I only realised how to solve the complex perimeter question in the last 5 secs of the exam T.T Only managed to scribble down the cosine rule -.-;

Dead serious. I know since every time assessment results are handed back, my 3U teacher also has a sheet of everyone's mark, mean, standard deviation etc for people to look at. Told you it's bad >.>;

Re: 回复: Re: CSSA ext2 trial For Q1, you know that a rectangle hyperbola has an eccentricity of the square root of 2. And since y = x is a symmetry axis, the rectangle hyperbola equation changes from xy = c into 2x = c. (Or 2y = c, doesn't matter) The value for x (Or y) is actually the value...

IIRC, you're given the range of rocket A as 72m, its time of flight to be 4.06s and its initial angle to the horizontal to be 48o. Then, rocket B makes an angle of 22o with the horizontal when its horizontal displacement is 50m. The question was to show that rockets A and B are in fact the...

If I told you that my class average for 3U this year has not surpassed 30%, would you believe your teacher then? XD

That's the entire point, isn't it? To hype people up? o.O
