Several combinatorial identities derived from series expansions of powers of arcsine
arXiv:2101.02027 · doi:10.53006/rna.867047
Abstract
In the paper, with the aid of the series expansions of the square or cubic of the arcsine function, the authors establish several possibly new combinatorial identities containing the ratio of two central binomial coefficients which are related to the Catalan numbers in combinatorial number theory.
