Tricky Tricky little Identities

[majinknight]

My friend sent me some Trigonometric proving identity questions to practise and i am usually good at them but i havent done them for a while so i have gotten a bit rusty plus these ones to me are very difficult so i would like some assistance.
Prove 1/1+sin + 1/1-sinx = 2secsquaredx.
ok so left side looks hardest so i started with that and did it first. It may look confusing writing the divisions.

1/1+sinx + 1/1-sinx
1/1+ cosx/cotx + 1/cosx
cotx+1/cosx + 1/cosx
cotx+1/cosx + 1
cscx/cosx +1
Ok so that is where i have gotten to and it doesnt seem like i can get it to equal the right side. I think i have screwed up a step and i would like any assistance if possible. Please help

You are making it look harder than it is... Just a 3 step problem.

\frac{1}{1+sinx} + \frac{1}{1-sinx} = \frac{2}{cos^2(x)}
\frac{2}{(1+sinx)(1-sinx)} = ...
\frac{2}{1 - sin^2(x)} = \frac{2}{cos^2(x)} = 2sec^2(x)

Oh you skipped step where you make bases same but ya it works, thankyou very much.
