Does Terry Lee put up 2U solutions or does no one care about 2U?
Nope. Terry Lee only does Ext. 1 and 2

But you can find general, 2 unit, ext. 1 and 2 at itute.com.

Unlike Carrotsticks and Terry Lee, itute take their time getting solutions up. Maybe in a few weeks.

The Board of Studies will also publish solutions - but much later. Maybe even next year!

Just wondering, for Question 16b, if I resolve the forces for iv and v, would I be able to get 1 mark each? For iv, I just wrote and for v, I wrote .

I wrote this aswell, but because S'PS is not 90 you cannot say CosB, you need to say sin <QPS (confirmed by Carrot). Hopefully they'll be nice to us and award us a mark but it's doubtful [since incorrect].

Crap. I didn't realise that because I forgot that P lies on an ellipse, not a circle.

Will I get anything for the e^x volumes question if I did exactly what u did, BUT I replaced the 4-x with 3-x? I would think since I got so close to the answer and obviously knew what I was doing, even if I messed up 1 number, I should at least get 1/4 right?
thatd probs be 3/4 wouldnt it? carried on errors... as long as you did an ibp

How is the curve sketching marked?
Is it 3 for right graph and 0 for anything else?

O yea, also with curve sketching, I slightly messed up x intercepts of 2nd graph, but shape is identical, as well as clearly distinguishable y intercept rather than (0,0), what would I get for it? 2/3 or 3/3?
