opposite for me, studied tonnes of physics and screwed it while found maths easy without study

17, sub x = a*tan@ 18, sub x = a*sin@ 19, sub x = a*sec@

wtf is with all these 1st's and 2nd's i haven't got mine back but i'm expecting some ranks to be in the 3 digits

either will work

doesn't anyone here favour rts[real time strategy] games? you actually have to think rts games. like the best way to assult the opponent, and balance your creation of armies with gathering resources etc

if your posting at 2:11 when ur supposed to be at school, no. kidding u should be able to get 94 quite easily, from ur ranks ur probably average about top 10% of ur school (not higher cause of other subjects) and ur school is ranked top 20% if its in top 100

no\: question\: again?\: rationalise\: the\: denominator: \frac{1}{\sqrt[3]{2}+1}

what about mc donalds drinks and juice/milk poppa's for the straws?

wait wait wait, does this mean the ranks are not the only important thing? lets say if u come first by 1 mark or first by 20 marks will it make a difference?

ok i'm probably wrong cause that Ko guy is pro at physics, but i wasn't talking about the velocity the earth is travelling relative to the sun but rather the fact the the earth spins, if the reference frame is with respect the the centre of the earth the fact that the earth rotates should still...

i don't think many people will get it if they have never seen this method b4

fish, and i'm not a vegetarian

Re: 回复: Re: integration what happens if the question says "using the substitution u=..." this occurs often in 3u papers

i think its a... cause the earth does spin from west to east and you do add the velocities since the reference point is not the moving launch point but rather the fixed point centre of the earth v= 2pi(r)/t ~=465m/s its not a major enough difference so that if 1 orbits the other won't though...

i thought the UAI was a ranking system, doesn't that mean the median would be be 50?

am i the only one who has half years after the holidays and is still doing them?

examiner left the room (god knows why) everyone cheated, but since its ranks it didn't really matter (SDD exam)

ibp can work u= arcsin(x) v' = 1/sqrt(1-x^2) u'=1/sqrt(1-x^2) v = arcsin(x) S[arcsin(x)/(sqrt(1-x^2)]= arcsin^2(x) - S[arcsin(x)/(sqrt(1-x^2)] 2S[arcsin(x)/(sqrt(1-x^2)]= arcsin^2(x) S[arcsin(x)/(sqrt(1-x^2)]= 1/2(arcsin^2(x)) but yea... it does suck

umm... i filled in the application but don't have a ticket. the file sent by email is an unknown file type so i can't open it if thats the ticket

d/dx[arcsin(x)]=1/sqrt(1-x^2) => dx/sqrt(1-x^2) = d(arcsin(x)); thats how we were taught at least and no i'm not posting during school
