FSMQ Additional Mathematics - 30th May 2012

I got 9.5 :/ what did you substitute in for t?

please somebody tell me they got 9.5m for max height haha

You know for the question where you had to find the co ordinate for D I dunno what I did but I got either (3,0) or (0,3) my working out wasn't too good I put down " to get from point B to point M you go -4 across and -3 down therefore D is..." I may pick up a mark if I'm lucky :s

I missed out the last question
HOW were we supposed to work it out?

(2+h)^3=8+ah+bh^2+ch^3

(2+h)(2+h)(2+h) = (8+12h+6h^2+h^3)

So a = 12, b = 6 and c =1.

I can't remember the question to the part b bit! (I only did the first three parts, I didn't do the last two!)

i think i got 41.8, 138.2 and 270

(0,3) sounds about right. I substituted it into the midpoint formula, which turned out to be quite easy after my previous attempts

I was quite surprised at the last question it didn't seem to be in the syllabus

I think the paper was slightly harder than all the past papers, so the grade boundaries will probably be quite low.

The last question everyone seemed to struggle with, but if anyone has seen the proof for differentiation then it's actually really easy. All the 'h's end up becoming so small they can be ignored so you are just left with the constant.

In my opinion the hardest question was where you had to find D on the circle. I ended up using vector MB to work it out because I couldn't think of another way. I ended up with D(0, 3) which I checked into the equation and it does lie on the circle.

*Might have been D(3, 0), I can't remember which way around it was.

I think I've got 83 out of 100?! Is that an A do you think?

Yes
