Abstract

In a series of recent works, we have provided a number of explicit expressions for the derivative of the associated Legendre function of the first kind with respect to its degree, [Pνm(z)/ν]ν=n[\partial P_{\nu}^{m}(z)/\partial\nu]_{\nu=n}, with m,nNm,n\in\mathbb{N}. In this communication, we use some of those expressions to obtain several, we believe new, explicit formulas for the derivatives dm[Pn(z)ln(z±1)]/dzm\mathrm{d}^{m}[P_{n}(z)\ln(z\pm1)]/\mathrm{d}z^{m}, where Pn(z)P_{n}(z) is the Legendre polynomial.
