# Edexcel C3 exam. Papers or Book? watch

1. I've done all the solomons and all the edexcel papers, but there is this topic that comes in the solomons and in the book, it is, however, not in a single edexcel papers. Is there any point going over said topic in the book, just incase they decide to throw this question out. Im of to look at the spec now, so it may say there.

the sums and differences of sines and cosines, but that too actually , ive seen one arcsin/arccos question in jan 07 Q8
11. the sum of the differences of sines and cosines is actually in the spec it never came up, but, knowing our luck, it will come tomorrow and feature as THE proof question. So, yeah, learn the proof. Using it's easy - especially if you've done the Solomon G.

off topic: why did you decline southampton? ( )
