Step-by-Step Mathematical Derivation

1. Given Input Coordinates:
  • Origin P1: (40.7128°, -74.006°)
  • Destination P2: (51.5074°, -0.1278°)
2. Model & Ellipsoid Reference:WGS-84 / Earth Sphere R = 6,371 km
3. Governing Geodesic Formula:d = 2R × arcsin(sqrt(sin²(Δφ/2) + cos(φ1)cos(φ2)sin²(Δλ/2)))
4. Variable Substitution:R = 6,371 km, Δφ = 10.7946°, Δλ = 73.8782°
5. Interpretation & Practical Application:

The great-circle flight distance between (40.7128, -74.006) and (51.5074, -0.1278) is 5570.23 km.

Mathematical Formula

Geodesic Distance = Haversine great-circle formula on Earth sphere (R = 6,371 km)

Overview & Explanation

Calculates the straight line (geodesic great circle) flight distance between two points on Earth.

How It Works

  • Applies Haversine trigonometric formula on mean Earth radius R = 6,371 km.

Practical Applications

  • Flight distance estimation.
  • Global distance research.
