Well, but I don't have so much experience in seprating fractions :'(. How do you seprate the fraction
[tex] \frac{1}{1\pm u} [/tex]

Those can't be decomposed further, but:
[tex]\frac{1}{1-u^{2}}=\frac{1}{2}(\frac{1}{1+u}+\frac{1}{1-u})[/tex]
[tex]\frac{1}{1+u^{2}}[/tex] cannot be partially fractiondecomposed in real partial fractions.
