Ah yes I remember that question (did core 4 in Jan 13) as part of my revision. Try multiplying both numerator and denominator by 3sqrt3.

Hi
Thanks for helping, but why do we multiply both numerator and denominator by 3sqrt3. Here is a picture to try and help explain.

Ps sorry pic is upside down.

How'd you mean? I didn't use that identity in the picture, its just manipulating the fraction to the required form

Okay so the identity was used, but you get tanB= -1/root3

I just did this paper today and i dont get why 2a ii) is -1/ root3 and not 1/root 3

The question says the angle is obtuse, so if you look at the tan curve, +1/root3 gives acute angles and -1/root3 gives obtuse

27. Guys can we move discussion about the C4 exam to this thread

http://www.thestudentroom.co.uk/show....php?t=2285046

It was started earlier and so has more pages. No point having two threads about the same exam- why not share everything in one place
