In Mathematica 8, with the command
In[1]:= Wronskian[{LegendreP[n,xi],LegendreQ[n,xi]},xi]
we get
Out[1]= -(((1 + n) (LegendreP[1 + n, xi] LegendreQ[n, xi] -
2
> LegendreP[n, xi] LegendreQ[1 + n, xi])) / (-1 + xi ))
FullSimplify does not simplify the above expression to 1/(1-xi^2).
The result given by Mathematica is correct, but not as compact as
1/(1-xi^2).
