I personally thought it was really hard, any ideas what the grade boundaries might look like???

Think I got somewhere in the 50s.

Question 11 was a b****
Part from that think i got through majority. Back page was pretty difficult though, asymptotes of inverse tan???

I would be interested in boundries, not sure what they might be though

Rekon i got sumwhere between 55 and 65, a B would do me very nicely lol

Way harder than anything else I have done before, well the first nine or so questions were quite easy but after that it just went downhill lol

I reckon I got between 40-50%. I don't really need this anyway so I won't be too bothered if I don't pass. I put in an effort for the sake of pride though.. lol.

I didn't have enough time. And everyone else in my class left early.

Off the top of my head:
1) a=1, b=-8, c=24, d=-32, e=16
2) f'(x) = 2cos2x e^(sin2x)
dy/dx = 4^(x^2 +1) 2xln4
3) other roots were 3-3i and -6
4) ln(8/9)
5) b)det(a)=3, det(ab)=96x, det(b)=32x
6) cos x = 1 - x^2/3 + x^4/24
f(x) = 1/2 - x^2 + x^4/3
7) p=10, q=-113
8) y=(Ax+B)e^-3x + (1/25)e^2x
9) Proof. the middle sum was 2q - 12q^2
10)first part, 1/24. Second part, pi/24
11) 4x+2y-3=0
12)Proof. Multiply both sides by (1+a), expend RHS and note that this is greater than 1+(n-1)a
13)y=root(2) - x, k=-1
14)Can't remember what I had for the function, but:
b)25k=3.310
c)yes, it was only slightly more than 1m
d)roughly 3.6m
14)a) No value of s and t that satisfies x=x, y=y, z=z simulateneously
b)Can't remember
c)(-1,0,2), P lies on L1 when s=-1
d)root(6)
15.a)y= +/- pi/2
b)pi/8 - (ln2)/4
c)pi/4 - (ln2)/2
There'll probably be a few slips in there though.

So if it's more difficult that last years, they'll hopefully put the pass marks down a bit? *prays*
About a third of my answers look similar to yours but they are the third I think theres an offchance I could be right.

There's a good chance a few of those I posted will be wrong by the way, so I wouldn't be to concerned if you've got something different
