Thread: Preparing for next year

Hi,

I've asked for a list of questions from a teacher to do over the holidays. I'm struggling to use the text book to help me.

Could someone provide HOW to do these questions, as I just want to get an idea of what I'm getting next year.

Thanks.

1. Prove that:
a)
b)

2. Simplify

1. Prove that:

b)

2. Simplify

1. In both cases apply the compound angle formula for sin(A + B).

2. Substitute the double angle formulae and simplify.

Please refer to my comments in another of your threads.
