yeh k 2[tanx] with terminals of 1 and -3^0.5/2 with my calculator in rad.. 2[1.5574...- (-2.773...)] 2[4.330869378..] 8.661....

I still do not understand why my answer is different...baha

Hey Namu check out my thread in the 2U maths section. It's from the 08 CSSA trial...is the answer wrong or am I dumb? lol

Okay this is a really simple question but I just can't get the answer for some reason (I put my calculator to rad). Either the answer's wrong or I'm a complete dumbass. find the definite integral of 2sec^2x with terminals 1 and -3^0.5/2 the answer is 5.5 to 1 dp, I got 8.7.

lol srs? I thought it was the other way around. We get CSSA papers for trials though? I'll do a combo of both.

sweet! are cssa papers the way to go for 2 and 3U?

That's like impossible lol. Personally I'm accustomed with say 95% of the course so I'll just go with the flow. Damnn does that mean crazy workload next term before trials? haha

Hey man are they going to cut out content from our 3U trials because my class has seriously only done like 50% of the course. Was everything tested last year?

haha i got 2.4 x 10^-4 mol/L as well...same answer as part (a) lol simple Q

Haha everybody seems confident that I'll do well. I must admit though for maths the assessments are too easy at times. Five people got 100% in the last 3U test! Anyway thanks for the closure everyone =P

hmm seems like C is in favour..makes sense though but i find this question really ambiguous.

baha oh yeah i dropped from 2nd in adv english and chem last term i was so devastated! i doubt that i can regain that rank for english...assessment in week 1 and no idea what to do! but wow estimates are high..in reality i'd be stoked with 95 or thereabouts.

wow u did well...which school?

Ranks so far with trials coming up next term. My school's ranked 94th SOR 1U- 7/109 Eng Adv-7-10/64 Chem-5/25 Eco-2/36 Maths 2U-1/75 Maths 3U-4/48 Eng Ext i imagine 15-20/23 but probs won't count hopefully going to boost my chem rank when the trials are done.

lol true! already had enough of them AT school. hmm I don't really get wasted or do any of that shit. Plus I'm going to Tokyo instead...wayyyyy more fun. Hopefully swine flu will be gone by then otherwise I'll be quarantined and stuff for being an Australian. Oh but I might miss the skanks ):

It says that you were active at 6:58pm today and I posted my last message at 9:51am today discerning why you hadn't replied to my shit. Are you scared of me? We should burn money together some time.
