Motivated by the recent work on the symmetric domains, this article investigates certain
features of symmetric domain which are caused by the secant hyperbolic functions. Geometric
characteristics of analytic functions associated with secant hyperbolic functions are discussed, which
include the inclusion results, structural formula, certain sharp radii results such as radius of starlikeness and convexity of order α. It also finds a radius for ratios of analytic functions associated with Euler numbers.
