    Proving Orthogonality of Legendre Polynomials P3 and P1

    legendre polynom in three dimension Hello, does anyone know the rule to obtain a general P^n Legendre Polynomial in three dimension? thanks!

    I wronged again...now maybe! Hi, the integral that I have to solve is this: \begin{equation} \int{d^3u u_a u_b u_c u_d u_e u_f} \end{equation} If I have the T^6 of the Legendre polynom in three dimension all would be done! silvia

    Hello, can anyone help me? I have to solve this 3-dimension integral: ui*uj*uk*ul du where u is a versor. Is it equal to: delta(i,j)*delta(k,l)+delta(i,k)*delta(j,l)+delta(i,l)*delta(j,k)? where delta=delta Kronecker if yes what about the the integrals: ui*uj*uk*ul*um du and...
