The Edexcel C3 (14/06/12 - AM) Revision Thread

@Everyone:
Not the C2 kind, the one where it's like F(x) = Q(x) x divisor + remainder
and it's all like (Ax2 + Bx + C)(x-3) + D and you need to "compare the coefficients". Gah, it's just tedious and I don't like it!

Remember it's the negative of the number. When dividing by (x-c) the remainder is f(c).

That's not a number given, it's a divisor. I tend to think in terms of roots or factors, so I take the given x value to be the negative of the number inside the divisor.

Good luck everyone, I hope something favourable comes up for you.

We've covered pretty much everything I hope, at least to the extent that we are at least prepared for a weird question!

On a lighter note, I just did the arccos/arcsin Jan 2007 Q8 very nicely. But that's most likely thanks to reading all of the explanations earlier on in the thread... Love you, people of TSR. <3

Good luck, everyone! Hope the paper's nice for us!

Well guys, this thread has definitely made C3 cramming more fun, and also been helpful. I guess I won't be coming here again after I go to bed tonight, so I'll see you all on the other side! (In Arsey's midnight solutions thread :tongue:

)
If you need something solved or explained urgently PM me and I'll answer at 6:30ish when I wake up, or quote me if it's in the next 20 mins or so.

Wait, so what are you saying they would be asking us? I was saying if they asked what is the remainder when blahblah is divided by (x-2).
