WebThe first variation of area refers to the computation d d t ω t = − W t, H ( f t) g ω t + d ( ι W t ∥ ω t) in which H(ft) is the mean curvature vector of the immersion ft and Wt denotes the variation vector field ∂ ∂ t f t. Both of these quantities are vector fields along the map ft. WebNov 24, 2009 · Theorem 1 (First Variation Formula) For variations fixing the endpoints In particular, since can be really chosen arbitrary with , we see that a curve locally minimizes the energy only if it is a geodesic. There is a reason for this. First, by Cauchy-Schwarz, we have There is equality precisely when moves at constant speed, i.e. is constant. small saffiano leather 3-in-1 card case

WebDirect Variation. The statement " y varies directly as x ," means that when x increases, y increases by the same factor. In other words, y and x always have the same ratio: = k. where k is the constant of variation. We can also express the relationship between x and y as: y = kx. where k is the constant of variation.
