I am trying to understand how some equations are obtained in some lecture notes I have.
This is my starting equation-http://i423.photobucket.com/albums/pp315/skaboy607/StartEquation.png [Broken]
And I need to satisfy these conditions
And somehow get to here
The Attempt at a Solution
I've stared at it for a while now and just don't get it. Wouldn't the square come down in front of the brackets? and surely the other constants would dissapear?
any help most appreciated..
