►The classical method of reducing (19.2.3) to Legendre’s integrals is described in many places, especially Erdélyi et al. (1953b, §13.5), Abramowitz and Stegun (1964, Chapter 17), and Labahn and Mutrie (1997, §3).
…If no such branch point is accessible from the interval of integration (for example, if the integrand is and the interval is [1,2]), then no method using this assumption succeeds.
