Just gonna use " / " for divided by:
Express sin2A / 1 - cos 2A in terms of tanA only.
Express cos 2A - cos(squared)A / 1 + cos2A
any help at all would be much appreciated !! = )

You might find the following identities useful:
And, of course, tan(x)=sin(x)/cos(x).
If you use these identities you should be on your way...
