Examples
The first five Legendre polynomials are:
\(\ds \map {P_0} x\) | \(=\) | \(\ds 1\) | ||||||||||||
\(\ds \map {P_1} x\) | \(=\) | \(\ds x\) | ||||||||||||
\(\ds \map {P_2} x\) | \(=\) | \(\ds \dfrac 1 2 \paren {3 x^2 - 1}\) | ||||||||||||
\(\ds \map {P_3} x\) | \(=\) | \(\ds \dfrac 1 2 \paren {5 x^3 - 3 x}\) | ||||||||||||
\(\ds \map {P_4} x\) | \(=\) | \(\ds \dfrac 1 8 \paren {35 x^4 - 30 x^2 + 3}\) |
