Official text: dlmf.nist.gov/3.8
Relevant locators: §3.8(i), equation 3.8.3 and following definitions of local order of convergence; §3.8(iii), equation 3.8.6 and the Secant Method paragraph, which distinguishes the secant method from bracket-preserving alternatives. The derivations and calculations in the solutions are given independently.
Official NIST DLMF section 5.12. Equation 5.12.1 gives Euler's integral for the beta function and its expression as a ratio of gamma functions, with positive real parts of the two parameters. The integral identity supplies normalization and shifted-parameter moments for the beta distribution.
Chapter authors: Ranjan Roy, Frank W. J. Olver, Richard A. Askey, Roderick S. C. Wong, William P. Reinhardt. Their names are given on the official chapter landing page.
