WebThe trick is to convert from the t -parameterization to one in terms of f, because in terms of t the radius R is easy to compute (via the Pythagorean theorem). Its square is the sum of squares of the components of the … WebEnter latitude and longitude of two points, select the desired units: nautical miles (n mi), … WebThe Radius at Geocentric Latitude block estimates the radius ( r s) of an ellipsoid planet at a particular geocentric latitude ( λ s). The following equation estimates the ellipsoid radius ( r s) using flattening ( f ¯), geocentric latitude ( λ ¯ s), and equatorial radius ( R ¯): r s = R 2 1 + [ 1 / ( 1 − f) 2 − 1] sin 2 λ s. grocery store out of food
