It definately was 36 units, checked it on graphics calculator.

Thought both papers went well, Paper One was a bit harder than Paper 2 I thought.

My theories for pretty much all the questions were sound I think, but I've made a few errors , llike not putting +C after integration sad.gif and the graph sketching forgetting to add 3 etc.

Hail to the the Chief for making the answer -1/4.
That's what I said but nasty friends were telling me it was positive.

Very annoyed though that there wasnt any optimisation or completing the square etc. I'm a pro at those.

Also, the whole a.(a+b+c+) thing, what's that all about?

I didnt get this question right, I think i must have dont eh same as you, did you differentiate etc then turns out to be one?

The right answer is that you take the expression its something like (3x...) and make it into two brackets, one solution is -1/4 and the other is 2, therefore the answer is 2 as it does not recur, while -1/4 does recur (recurrance happens when x is in between 1 and -1)

a.(a+b+c) = a.a + a.b + a.c?

a.a = 3*3
a.b = 0
a.c = 3 * 2 * cos(sin-1(2/3))

and add 'em together. That's what I did... unsure.gif

Comes to 13.5.
