单词	Legendre polynomials
释义	Legendre polynomials Mathematics A set of polynomial solutions {P_n(x)} to Legendre’s differential equation are generated by the expansion of $\frac{1}{\sqrt{(1 - 2 x t + t^{2})}}$ as the coefficients of tⁿ. Alternatively they can be found by Rodrigues’ formula $P_{n} (x) = \frac{1}{2^{n} n!} \frac{d^{n}}{d x^{n}} {(x^{2} - 1)}^{n} .$
