WebNov 16, 2024 · Using the first \(ds\) will require \(x\) limits of integration and using the second \(ds\) will require \(y\) limits of integration. Thinking of the arc length formula as a single integral with different ways to define \(ds\) will be convenient when we run across arc lengths in future sections. WebThe length is defined as L ( γ) = ∫ γ d s. So the first variation is d d c L ( γ + c ϕ) c = 0 = d d c ∫ γ + c ϕ d s c = 0 = ∫ γ + c ϕ ∇ γ + c ϕ ⋅ v c c = 0 (where v c is the velocity of the curve γ + c ϕ ) = ∫ γ + c ϕ v c ⋅ κ c ν c c = 0 where κ c and ν c are the mean curvature and unit …

The first derivative of x is 1, ... Mean curvature is closely related to the first variation of surface area. In particular, a minimal surface such as a soap film has mean curvature zero and a soap bubble has constant mean curvature.
WebA typical problem in the calculus of variations involve finding a particular function y(x) to maximize or minimize the integral I(y) subject to boundary conditions y(a) = A and y(b) = B. The integral I(y) is an example of a functional, which (more generally) is a mapping from a set of allowable functions to the reals. WebMay 6, 2012 · First Variation Formula.
