Relating to or having the mathematical form of a catenary; shaped like the curve made by a hanging chain.
From catenary (which comes from Latin catena, chain) plus -ian (relating to). Describes the specific mathematical properties of catenary curves.
The catenary curve is mathematically identical to a hyperbolic cosine function, and it appears everywhere in nature—from spider webs to power lines to the Gateway Arch—yet most people never notice this hidden pattern.
