To show that two Legendre polynomials(Pn and Pm) are orthogonal wht is the test that i have to use? is it this? [tex] \int_{-1}^{1} P_{n}(x)P_{m}(x) dx = 0 [/tex] in that case to prove that P3 and P1 are orthogonal i have to use the above formula??
legendre polynom in three dimension Hello, does anyone know the rule to obtain a general [tex]P^n[/tex] Legendre Polynomial in three dimension? thanks!
