- Birmingham: 52°29'N, 1°54'W
- London: 51°30'N, 0°08'W
Using these coordinates, we can calculate the initial bearing of London from Birmingham using the following formula:
Initial Bearing = arctan((Δ Longitude * cos(Latitude 2)) / (Δ Latitude))
Where:
Δ Latitude = Latitude 2 - Latitude 1
Δ Longitude = Longitude 2 - Longitude 1
Latitude 1 and Longitude 1 are the coordinates of Birmingham.
Latitude 2 and Longitude 2 are the coordinates of London.
Plugging in the values:
Δ Latitude = 51°30'N - 52°29'N = -0°59' (Note: Negative sign indicates the difference is South)
Δ Longitude = 0°08'W - 1°54'W = 1°46'W
Initial Bearing = arctan((-1.77° * cos(51°30')) / (-0.98°))
Initial Bearing = arctan(1.69)
Initial Bearing ≈ 60.6°
Therefore, the initial bearing of London from Birmingham is approximately 60.6°.
