Hi, I tried doing this equation over and over, but I can't seem to get it! I've had sleepless nights for the past week...lol. So, please help me and put me out of my misery, I beg you...

I need to prove that:

$\displaystyle \frac {1+sinA}{cosA} + \frac{cosA}{1+sinA} = 2secA$

this is what I came up with so far on the LHS, using $\displaystyle 1=sinA+cosA$:

$\displaystyle = \frac {(sinA+cosA)+sinA}{cosA} + \frac {cosA}{(sinA+cosA)+sinA}$

$\displaystyle = \frac {sinA+cosA+sinA}{cosA} + \frac{cosA}{sinA+cosA+sinA} $

$\displaystyle = \frac {(1-cosA)+cosA+(1-cosA)}{cosA} + \frac{cosA}{(1-cosA)+cosA+(1-cosA)} $

$\displaystyle = \frac {2-cosA}{cosA} + \frac{cosA}{2-cosA} $

And that's where I got stuck. I don't even think my working out is right...

PS. I tried using

Wolfram|Alpha to solve it but it just tells me that the equation is true and gives me alternate forms, it doesn't show me steps which I need in order to fully understand, ya know?
