Calculus of variations geodesic
Web1 The differential equation is, d d x ( R v ′ P + R v ′ 2) = 0. From elementary calculus we have that if the derivative of a function is zero then it is a constant function, R v ′ P + R v ′ … WebCalculus of variations is the area of mathematics concerned with optimizing mathematical objects called functionals. Calculus of variations can be used, for …

WebGeodesic is the shortest line between two points on a mathematically defined surface (as a straight line on a plane or an arc of a great circle (like the equator) on a sphere). Geodesic is a curve whose tangent vectors remain parallel is they are transported along it. c Daria Apushkinskaya 2014 Calculus of variations lecture 6 23.

WebMar 24, 2024 · A branch of mathematics that is a sort of generalization of calculus. Calculus of variations seeks to find the path, curve, surface, etc., for which a given function has a stationary value (which, in physical problems, is usually a minimum or maximum). Mathematically, this involves finding stationary values of integrals of the form …
