A catenary curve is the curve formed by a cable hanging between two points. The Gateway Arch in St.Louis is an inverted catenary curve. For an electric power line between two poles, one may be interested in the amount of sag at the midpoint between two poles. Below we do the calculations for discrete links. If we assume the line is continuous, there is a closed form solution involving the hyperbolic cosine function.
