Heya, I'm going to put this in the Maths forum for you as you should get more responses there.

You should also check out the forum to see if there's any other threads there which might be helpful to you! http://www.thestudentroom.co.uk/forumdisplay.php?f=38
Which questions? All of them?

No-one's going to do all those for you!

Can you show some working or at least tell us what ideas you've had so far?

Just use the standard trig identities and rearrange accordingly.

1+cot2θcsc2θ[br][br]1+tan2θsec2θ[br] 1 + \cot^2 \theta \equiv \csc^2 \theta[br][br]1 + \tan^2 \theta \equiv \sec^2 \theta[br]
