Web1 de jan. de 2024 · In this paper we discuss a general framework based on symplectic geometry for the study of second order conditions in constrained variational problems on curves. Using the notion of -derivatives we construct Jacobi curves, which represent a generalisation of Jacobi fields from the classical calculus of variations, but which also … WebA bit of elementary calculus: The angle that the path makes to the x-axis is such that tan 2= dy dx = y0. We also have arc-length sde ned by ds = dx2 + dy2. Putting these together, we have sin = y0 p 1 + y02 = dy ds; cos = 1 p 1 + y02 = dx ds: It is also useful to derive from these that = d ds = y00 (1 + y02)3=2
