Geodesic coordinates
WebJun 5, 2024 · If the geodesic coordinates are such that to the straight lines issuing from a point $ P $ in all directions there correspond geodesics on which $ ( D / d t ) ( d \gamma / d t ) = 0 $, then they are called Riemannian coordinates. Comments. Riemannian coordinates are better known as normal coordinates or geodesic polar coordinates in the West. WebThis is called geodesic polar coordinates from x. Proposition 11.1.1 In geodesic polar coordinates the metric takes the form g(∂ r,∂ r)=1; g(∂ r,u)=0, for any u∈ TSn−1. In other words, the image under the exponential map of the unit radial vector in T xMis always a unit vector, and the image of a vector tangent

Thus the geodesic on a sphere is the path where a plane through the center intersects the sphere as well as the initial and final locations. reddit chow chowWebquantity. We can exploit this to solve geodesic equations. 3 Example: The Plane The procedure for solving the geodesic equations is best illustrated with a fairly simple example: nding the geodesics on a plane, using polar coordinates to grant a little bit of complexity.
