Evaluation of Integrals involving Legendre Functions












0












$begingroup$


I am trying to evaluate these integrals:



1)$$int_1^{coshξ_0}frac{P_{n-1/2}(ζ)ζ,mathrm dζ}{sqrt{ζ-1}},$$
2)$$int_{coshξ_0}^inftyfrac{Q_{n-1/2}(ζ),mathrm dζ}{sqrt{ζ-1}},$$
where $n$ is any non-negative integer.



Mathematica is unable to evaluate these integrals. Any help will be appreciated.
