Associated Legendre polynomials in Mathematica

I'm trying to look at the Associated Legendre Polynomial, so I plugged it into Mathematica to see the values for different input. From wikipedia: $$ p_l(x)=\frac{1}{2^l l!}\frac{\partial ^l}{\partial …

Proof associated Legendre polynomials are orthogonal: integral doesn't solve

Wondering why Mathematica can't solve this integral: Integrate[ LegendreP[l1, 1, x] * LegendreP[l2, 1, x], {x, -1, 1}] Mathematica outputs: $\int_{-1}^1 P_{\text{l1}}^1(x) P_{\text{l2}}^1(x) \, d …
