Hi,
> f = (2*l+1) / (2*t) * Integral(legendre(l, (1-R**2+t**2) / (2*t)) * > exp(-alpha*R), (R, 1-t, 1+t)) BTW: probably this integral does not have a closed form, not even in terms of pFq or even higher functions: http://www.wolframalpha.com/input/?i=Integral%28exp%28-R*alpha%29*LegendreP[l%2C+%28-R**2+%2B+t**2+%2B+1%29%2F%282*t%29]%2C+R%29 http://www.wolframalpha.com/input/?i=Integral%28exp%28-R*alpha%29*LegendreP[l%2C+%28-R**2+%2B+t**2+%2B+1%29%2F%282*t%29]%2C+R%2C+1-t%2C+1%2Bt%29 http://integrals.wolfram.com/index.jsp?expr=Exp[-x*a]*LegendreP[l%2C+%28-x**2+%2B+t**2+%2B+1%29%2F%282*t%29]&random=false -- You received this message because you are subscribed to the Google Groups "sympy" group.
