Proving Orthogonality of Legendre Polynomials P3 and P1

Click For Summary
SUMMARY

The discussion centers on proving the orthogonality of Legendre polynomials, specifically P3 and P1, using the integral test defined as ∫_{-1}^{1} P_{n}(x)P_{m}(x) dx = 0. This integral confirms that the polynomials are orthogonal if the result equals zero. Additionally, the Rodriguez formula is mentioned as a method for deriving Legendre polynomials in three dimensions, which is essential for understanding their properties and applications.

To show that two Legendre polynomials(Pn and Pm) are orthogonal wht is the test that i have to use?

is it this?
\int_{-1}^{1} P_{n}(x)P_{m}(x) dx = 0

in that case to prove that P3 and P1 are orthogonal i have to use the above formula??

What is the definition of "orthogonal" in this case?
 
you can also use rodriguez formula for this
 
legendre polynom in three dimension

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

thanks!
 
sorry, I wronged:the rule to obtain the general P_n Legendre Polynomial
