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.
