Today we use two equations to represent the mathematics
of the Gateway Arch:
y = 693.8597 - 68.7672 COSH(0.0100333 x) feet
for x between or equal to -299.2239 and 299.2239 for the
general arch shape and
Q = 125.1406 COSH(0.0100333 x) square feet area of a
cross section, that is the local shape. A short
"OWNER'S MANUAL FOR THE GATEWAY ARCH,
SAINT LOUIS, MO." uses
a graphing calculator approach to learning the mathematics
of the Arch with the above equations.
The following presentation of the mathematics of the Arch
is based on the history of the construction.
Please enjoy the history approach now.
