The direction between any two places on Earth can be calculated using the spherical trigonometry. We can use the following equation to do that Direction Angle =tan-1 (sin(longitude2 – longitude1)/cos(latitude1)*tan(latitude2)-sin(latitude1)*cos(longitude2-longitude1)) In spherical trigonometry values of latitude and longitude represent angles as in the following diagram: Example One famous example is The Islamic Qibla. Muslims need… Continue reading Directions On Map
