Thanks a lot. I can understand now. :)

Thanks - I've got it. :) May I ask you - how do you know what to do with this question in the first place? I mean, how do you know to mulitply by one (which I understand and make sense) but how to do you what to multiply with? I mean it could be sinx + cosx +1 or sinx - cos x + 1 or any...

Hi there, thanks a lot for your quick reply. I've done the multiplication and now I ended up with (sin^2 x - cos^2 x - 1) / (2 + 2sinxcosx -2sinx) I tried to further simplify into sin^2 x - 1 / 1 + sinxcosx - sin x, but then I'm stuck here.. wondering if this is the correct method...

Help! I spent 3 hours attempting this question. Prove the following identity : (tan x + sec x -1) / (tan x - sec x + 1) = tan x + sec x I've simplified Left Hand Side into cos and sine. Which ended up like this (sine x - cos x + 1) / (sine x + cos x -1) Then I'm stuck. Any help is...
