Spherical longitudes

WebA spherical triangle is a figure on the surface of a sphere, consisting of three arcs of great circles. The shape is fully described by six values: the length of the three sides (the arcs) and the angles between sides taken at the corners. If the side lengths are given in angular measure, the shape description becomes independent of the sphere ...

WebAug 10, 2011 · 165. Here's the answer I found: Just to make the definition complete, in the Cartesian coordinate system: the x-axis goes through long,lat (0,0), so longitude 0 meets the equator; the y-axis goes through (0,90); and the z-axis goes through the poles. The conversion is: x = R * cos (lat) * cos (lon) y = R * cos (lat) * sin (lon) z = R *sin (lat ... WebOct 31, 2024 · The sides of a spherical triangle, as well as the angles, are all expressed in angular measure (degrees and minutes) and not in linear measure (metres or kilometres). A side of 50 ∘ means that the side is an arc of a great circle subtending an angle of 50 ∘ at the centre of the sphere. screenupdating vba https://plumsebastian.com
