Summary
On 2026-03-18, TravisEdwards-h1j (suspected to be a sock puppet of DamascusSteel) used Δlat × 111,132 m/° north + Δlon × cos(lat) × 111,132 m/° east
as a simpler flat-Earth approximation
to calculate a distance on the planet.
According to his math, the distance between lines of longitude scales by the cosine of the latitude which shrinks to zero at both the North Pole and the South Pole. Therefore, lines of longitude converge at the poles. This describes a globe.
