Legendre's elliptic integral, associated hypergeometric transformation formulas and explicit evaluations

D. Ritelli
M.A. Shpot

We study the implications of a hypergeometric transformation formula by Mingari Scarpello and Ritelli [Open J. Math. Sci. 2 84–92 (2018)] derived from results given by Legendre in 1825 and essentially extend its validity range. Applications include closed-form evaluations of hypergeometric functions 2F1 with different sets of parameters and arguments. Relations to special values of elliptic integrals of first kind in the singular value theory are established. Connections with a hypergeometric transformation due to Ramanujan and his explicit determinations of certain 2F1 functions are discussed.
