The Attempt at a Solution
I started by doing substitution: x=U+3/2 and y=W-1/2
So, it gave me http://img522.imageshack.us/img522/3172/clipboard02ly8.jpg [Broken],[/URL] but http://img167.imageshack.us/img167/8297/clipboard03db9.jpg [Broken],[/URL] so http://img175.imageshack.us/img175/3223/clipboard04xt2.jpg [Broken].[/URL]
Therefore, http://img237.imageshack.us/img237/2264/clipboard05iu8.jpg [Broken]
And, http://img377.imageshack.us/img377/615/clipboard06ez2.jpg [Broken].[/URL] Substitution z=W/U. Giving, http://img139.imageshack.us/img139/5639/clipboard07hb7.jpg [Broken] (*).
And, http://img399.imageshack.us/img399/2373/clipboard08qj2.jpg [Broken]
Rearranging gives http://img114.imageshack.us/img114/1830/clipboard09tm2.jpg [Broken].[/URL] Substitute in (*)
http://img140.imageshack.us/img140/8541/clipboard10bz2.jpg [Broken] => http://img140.imageshack.us/img140/6706/clipboard11ao0.jpg [Broken] => http://img135.imageshack.us/img135/8163/clipboard12ee3.jpg [Broken]
Dividing 1/(1+z2) and -z/(1+z2) and integrating gives:
http://img521.imageshack.us/img521/3638/clipboard13nj5.jpg [Broken].[/URL] But now I'm stuck :( because I can't solve this for z and go back to y and x :( maybe I made an arithmetical mistake or maybe there is a better method?
Thank you
