The time zone is three hours ahead of UTC , which is the same as Moscow Time, Arabia Standard Time, Further-eastern European Time and Eastern European Summer Time. As this time zone is predominantly in the equatorial region, there is no significant change in day length throughout the year and so daylight saving time is not observed. East Africa ...
Vincenty's formulae. Vincenty's formulae are two related iterative methods used in geodesy to calculate the distance between two points on the surface of a spheroid, developed by Thaddeus Vincenty (1975a). They are based on the assumption that the figure of the Earth is an oblate spheroid, and hence are more accurate than methods that assume a ...
Africa. Africa, the world's second-largest and second-most populous continent, spans across six different time zone offsets from Coordinated Universal Time (UTC): UTC−01:00 to UTC+04:00. [2] [3] As Africa straddles the equator and tropics, there is little change in daylight hours throughout the year [4] and as such daylight saving time is ...
A rhumb line appears as a straight line on a Mercator projection map. [1] The name is derived from Old French or Spanish respectively: "rumb" or "rumbo", a line on the chart which intersects all meridians at the same angle. [1] On a plane surface this would be the shortest distance between two points.
East Africa, also known as Eastern Africa or the East of Africa, is a region at the eastern edge of the African continent, distinguished by its geographical, historical, and cultural landscape. Defined in varying scopes, the region is recognized in the United Nations Statistics Division scheme as encompassing 18 sovereign states and 4 territories.
The position of the Sun in the sky is a function of both the time and the geographic location of observation on Earth 's surface. As Earth orbits the Sun over the course of a year, the Sun appears to move with respect to the fixed stars on the celestial sphere, along a circular path called the ecliptic .
The haversine formula determines the great-circle distance between two points on a sphere given their longitudes and latitudes. Important in navigation , it is a special case of a more general formula in spherical trigonometry , the law of haversines , that relates the sides and angles of spherical triangles.
A map of East Africa showing some of the historically active volcanoes (as red triangles) and the Afar Triangle (shaded at the center), which is a so-called triple junction (or triple point) where three plates are pulling away from one another: the Arabian Plate and two parts of the African Plate—the Nubian and Somali—splitting along the East African Rift Zone Main rift faults, plates ...
