Ok, i've tried this question, and it brings me to no answers. Please help!
Prove the following:
secY + tanY/cosY
= 1/cosY + sinY/cos^2Y
How should i attempt this question?? Am i even on the right track? Please help, much appreciated!

When I come across an unusual trig identity to prove, the first thing I do is try some arbitrary angle.
Since it is an Identity it should be true for any angle
e.g. Y = 30º
LS = sec30(1+tan30) = appr. 1.821
RS = 6csc30 = 12
No wonder you can't prove it, it is not true !
