ABSTRACT: Combinatorics has an important role in the field of computer science. Hypergeometric
series is an important branch of Combinatorics. By means of the hypergeometric method, we shall estab-
lish several series expansions of
and
. These results can be used to study the approximahte values
of the two irrational numbers just mentioned.
