# C4 trig watch

1. http://store.aqa.org.uk/qual/gce/pdf...4-QP-JAN12.PDF

Question 2

I did part (a) (i) and got 4/3
(ii) and got -root3/3

For part (b) I did the expansion and subbed in the values, but I can't get it into the form required.

Do you want to show your working it is very straightforward

Note : I used -1/rt3

I think that makes it much easier
3. got (4/3 -root3/3)/(1-4/3 x -root3/3) soz its messy I don't know how to use the latex thing. I tried manipulating it for a while but can't get it in the form required.

As I say easier if you leave it as -1/rt3

But same principle

Multiply by 3rt3
5. Got it now m=4 n=3. Thankyou
