WebSep 18, 2014 · Well, the formula is SA = 4πr2 just in case you want to calculate it! Wikipedia gives you the formula, as well as additional information. You could even use that formula to calculate how much the surface area of the moon is! WebApr 30, 2006 · Just a thought but couldn't you parameterise your ellipsoid using the 'usual' two variable parameterisation of a unit sphere but with an extra factor of a (or b) for the x and y components. eg. instead of writing x = sinucosv, let x = asinucosv. Similarly let y = bsinusinv and z = cosu.
10.1: Parametrizations of Plane Curves - Mathematics LibreTexts
WebThe sphere is a rational surface. The same surface admits many different parametrizations. For example, the coordinate z -plane can be parametrized as for any constants a, b, c, d such that ad − bc ≠ 0, i.e. the matrix is invertible . Local differential geometry [ edit] WebAug 30, 2024 · However, when one tries to parametrize the surface of a sphere, the parameters are non-symmetric. For example, using the standard spherical coordinates, … harris teeter navy yard washington dc
