2. Fabulous!! I finished today and went to a mates for a BBQ! It was great!! Good luck for Wednesday!!
3. ty.
tis this silly further maths. all my other exams were done by 10 june.
im thinking of having a barbecue using chemistry notes as fuel
4. Tee Hee! That's such a good idea! But personally I'd prefer physics notes! I (sadly) actually like chemistry!

(Ahhhhhhhhhhh 666 posts Undry1!!!)

Can anyone remember the answer for the vector question where you had to fing the perp. vector?? I think I got (4,0,?)
ahhhhhhhhh mad panik! what perpendicular question?????
6. pi/8 + 1/4 was one of the answers. q2 i think

tangents parallel to y axis have gradient infinity, so the bottom part of the fraction of dy/dx must equal 0
yeah, it didn't feel right setting the gradient equal to infinity so i just said dx/dy=0, same principle tho
8. the partial factor question
A=1, B=-1, C=2

i did it three times! got the right answer at the end

but i forgot to change the A in the (ii) bit~~~

which i used A=-1, B=-1, C=2!!~~~OMG

i remember (i) worths 5 marks and (ii) worths 5 marks as well

isn't it?

how much will it cost?~ or shall i say how much i can get?

yeah, it didn't feel right setting the gradient equal to infinity so i just said dx/dy=0, same principle tho
i find the f^-1(x) first
get x= (y.....)/(y...) first
and then differentiate it
get dx/dy = - (y^2+2) / ((y^2-2)^2)
which - (y^2+2) cant be 0~
so it doesn't parallel to y-axis

the partial factor question
A=1, B=-1, C=2
gah! that explains why i found the binomial expansion so nasty. i got A=1, B = -1/3 and C = 2/3
11. although having said that, a friend of mine got the same as me.
12. I'm sure that I got 1/3, 1 and something else for that binomial expansion. Oh well...
13. well hopefully im right and everyone else is wrong
