Hi:
When I give the command
Assuming[n \[Element] Integers,
Integrate[LegendreP[n,2,x]/(1-x^2),{x,-1,1}]]
I get
LegendreP[n, 2, x]
Integrate[------------------, {x, -1, 1}]
2
1 - x
instead of getting n(n+1)(1+(-1)^n)/2
However, if I put specific values of n such as 4,5 etc, I do get the
correct answer.
Regards
C. S. Jog
