yeah dont worry it was the one 3 unit formula i used to never be able to remember i just came up with a way to remember it i just remember its the opposite way to the differentiation of a log sounds stupid, but it works =]

the formula's x2=x1- [f(x1)/f'(x1)] thats all thats wrong

pretty sure this time last year my physics class was still on the first topic motion or whatever

short term effects probably include death

well lets say xy=42 the foci are (4rt2,4rt2) and (-4rt2,-4rt2) and the directrices are x+y=4rt2 and x+y=-4rt2 sorry but i dont really wanna type the proof out and im pretty sure the foci and directrices of rect. hyperbola's arent in the syllabus

the foci for all rectangular hyperbola xy=c2 are (+-rt(2)c,+-rt(2)c) and the directrices are x+y=+-rt(2)c

n+1C2 + n+2C2 = (n+1)!/(2!.(n-1)!) +(n+2)!/(2!(n!)) =(n(n+1)(n-1)!)/2!(n-1)! + ((n+2)(n+1)n)/(2!n!) =((n+1)n+(n+2)(n+1))/2! =(n+1)(2n+2)/2! =(n+1)2 therefore n+1C2 + n+2C2 is the square of n+1 New question: find the coefficient of x5 in the expansion of (x2-2/x)7

Therefore S 4cos^2@d@ = 2 S cos2@ + 1 d@ =2 [(sin2@)/2 + @][ =2 (sin(pi/3)/2 +pi/6 – 0 – 0) =Rt3//2 + pi/3 thats the answer i believe

yes they wanted an approximation using simpsons rule you wouldnt be answering the question

hey conics can you send it to me please??

oi someone do my question 1st!

because in the case of y=x+1/x, as x>>infinity 1/x becomes negligible so y>>x

in year 10 my maths teacher threatened me with detention if i didnt go in went in circles random answers after about q6 then had a little crack at the written questions and had a snooze for some ridiculous reason i ended up with a credit

guessing that last bit means 0<x<360 because it was worded really badly/ incorrectly now 5cos(x)-9sin(x)= rt(106)cos(x+atan(9/5)) so cos(x+atan(9/5))=2/rt106 x+atan(9/5)=acos(2/rt106), 360-acos(2/rt106) x= </x>acos(2/rt106)-atan(9/5), 360-acos(2/rt106)-atan(9/5) x=17deg51', 220deg15' (nearest...

my best mate does 14 units includiing 4 unit maths but his a freak id say start with both see how you go and if it affects your other marks drop which ever one u enjoy leeast

id suggest you get your trig up to scratch if you wanna do 4 unit its literally in every topic

or you could maybe do it via correspondance if they wont budge into letting you in?? not sure bout this though

well you know if you really wanted to do MX2 you shouldnt be cramming the night before for your MX1 yearly unless you can get >70% with no study but yeah if they say no, i guess you could beg??

no you are fucked

go to harajuku, probably the coolest place ive ever been really good clothes shops, mad funky fashion just be wary of the black guys on the street trying to sell you stuff they take you through these backstreets to their shops theyre alright i guess, i was just thinking they were gunna mug me...
