much needed luck... i dont like school

question 8 they just chuck in the scum off the bottom of thier well mathematically trodden shoes and dont care to give us a razor included

*turns to solutions* 1-x2+x4-... +x4n=1-x2+(x2)2-...+(x2)2n this is the sum of a GP with a=1 r=-x2 and N=2n+1 Sn = a(1-r^n) 1-r =1*[1-(1-x2)^(2n+1)] 1-(-x2) =1+(x2)^(2n+1) 1+x (since (-x2)^(2n+1)+-(x2)^2n+1) because 2n+1 is odd) =1+x^(4n+2) 1+x2

well the first 1 is a geometric progression (yes that thing that we did in 2u) dont ask me how to explain it, slept through that topic, just thaught this might help

my class and teacher have worked out the possible hsc qs from observing the past 5 years exam papers q 1 and 2 the same every year changeing graphs [1/f(x)] q3 volumes by sliceing anules, q3 volume shells q5 circle geo q6 or 7 elipse, no peramiters q4or5 hyperbola q3 circular motion...

as i have said in numerous threds, the corse has changed, since 01 its been ext 2, nad 02+ have been easier than thier predesessors

answers: i) 1/(n+1) ii) (-1)^n/(2n-1) ps these solutions are a page, what part exactly

the scale on the x doesnt have to corrospond to the scale on the y

hardest to date... but the corse has changed since then, which has made it easier, though it is still 4u

it6 also depends how small your 2 is, if it looks like a squiggle, they will most likly mark it right

hay, im not 1 for detail, i got 10 marks deducted it the trials for stupid mistaked, such as 4*6=10

ive got 2 calcs, though 1 has quotes all over the top of it(old 1, bored in english and geo yr 10) do you think they will mind???

it dosnt matter if the x and y axis are different scales, but you just have to make sure that all increments on the x are exual and the increments are equal. oh and you have to get the graph right aswell... that always helps

more like "if you can do 4u, you can understand forign languages and do any other subjuct, except ENGLISH"

lets just say that i will never watch a movie with the same blissfull ignorance that makes us happy

halfa page, twice as much as i wrote on the trials, hopeing for twice the mark :) dont like this module

3.5+.5+2=6 medium i guess OWEN SUX

i screwed this section, i wrote 1/3 of a page, btw i did owen, that sucked

well the majority of my supervisers are senile, and none are under 70 i swear, so i go home :)

this is my cooling down period (excuse for not studying) so i can sleep.... well it worked on mum, should realy be paniking about english, but in 13 hours NO ENGLISH EVER AGAIN!!! except the speaking part...
