    I was going to scan this question in, but my scanner has literally died on me . But if anyone has the Edexcel C3/C4 book can you look at page 177 and question 5a).

    I don't understand what they are asking for. Thanks for any help. xx

    Why do you do that? What is the question asking for?

    How would you do q15 on page 87. It's a similar question.

    Thats a tough un. Not my faves

    The thing is that I can spot how 30, 27cos and 18 sin are divided by 3, I just cant see how they get to it.
