On [https://www.youtube.com/watch?v=QN9VEIaNq0o&lc=UgzhMaydpFRREjGjGHt4AaABAg 2026-03-18], TravisEdwards-h1j (suspected to be a sock puppet of [[DamascusSteel]]) used <q>Δlat × 111,132 m/° north + Δlon × cos(lat) × 111,132 m/° east</q> as a <q>simpler flat-Earth approximation</q> 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.
