Fourier series calculator piecewise

The first property that the Legendre polynomials have is the Rodrigues formula: Pn(x) = 1 2nn! dn dxn(x2 − 1)n, n ∈ N0. From the Rodrigues formula, one can show that Pn(x) is an n th degree polynomial. Also, for n odd, the polynomial is an odd function and for n even, the polynomial is an even function. Example 5.3.1.
