cosh stands for Hyperbolic cosine, a math abbreviation.
Hyperbolic function defined as (e^x + e^−x)/2. Its graph, the catenary, is the curve formed by a chain or cable hanging under its own weight.
Example: A hanging chain follows y = a cosh(x/a), the catenary curve.
Usage notes
The Gateway Arch in St. Louis is shaped as a weighted, flattened catenary based on the cosh function. The identity cosh²x − sinh²x = 1 mirrors cos²x + sin²x = 1, with a minus sign. It is pronounced "kosh".
