Actually, I just realised that you are in fact correct. A=1, and B=0, meaning that the remainder is Ax+B = x, not 1.

Many apologies for this, I will decide what to do with the Question once I've marked them.

PS: Ignore the link attached to this post. This one contains the error. The most recent one is in the first post.

Same..

For the question about reasoning why f(x) < g(x) or something like that for 1 mark, i can't seem to express myself properly lol.

Could someone post up their reasoning?

That's because you subbed it in, and then differentiated.

You are supposed to differentate, and THEN sub it in. I had a friend make the same mistake.

Umm, things that jump out at me- Yeah I got the remainder as x as well so that's good :)

The last question demolished me- got a bit of the binomial and then nothing for projectile lol. I couldn't get the first parabola question (Show that p^2+pt+2=0) or the last part of the simple harmonic in Q13 or the last part of the other motion question in Q13.

All up- very sexy paper. Will be interested to see the marks and stuff- I got raped lol

I was gonna be like: LOOK AT TEH GRAPH. Not very convincing.



Shet. That doesn't work...maybe b / and or a are 0<a,b<1...awks.

Did anybody use the trig identity:

sin^2x + cos^2x = 1

To do the Simple Harmonic Question? Or did you all actually try to differentiate it twice etc etc.
