# Article : Lagrange polynomial calculator - Editor I wrote this calculator to be able to verify solutions for Lagrange's interpolation problems. In these problems you are often asked to interpolate the value of the unknown function corresponding to a certain x value, using Lagrange's interpolation formula from the given set of data, that is, a set of points x , f(x) .

2021-04-07 · The partial differential equation (1+f_y^2)f_(xx)-2f_xf_yf_(xy)+(1+f_x^2)f_(yy)=0 (Gray 1997, p. 399), whose solutions are called minimal surfaces. This corresponds to the mean curvature H equalling 0 over the surface. d'Alembert's equation y=xf(y^')+g(y^') is sometimes also known as Lagrange's equation (Zwillinger 1997, pp. 120 and 265-268).

Find more Mathematics widgets in Wolfram|Alpha. Lagrange Multiplier applications. You can use the Lagrange multipliers calculator for various purposes, such as to find out the maximum margin classifiers, model comparison, linear discriminant analysis, regularized least squares, and machine learning. For geometrical aspects of the calculus of variations, the representation of the Euler-Lagrange equations as the components of a differential bi-form is very useful. The third calling sequence EulerLagrange( ω ) returns a list of m differential bi-forms of vertical degree 1 less than the vertical degree of ω .

### which is derived from the Euler-Lagrange equation, is called an equation of motion.1 If the 1The term \equation of motion" is a little ambiguous. It is understood to refer to the second-order diﬁerential equation satisﬂed by x, and not the actual equation for x as a function of t, namely x(t) =

Warning 2 Y satisfying the Euler-Lagrange equation is a necessary, but not sufficient, condition for I(Y) to be an extremum. In other words, a function Y(x) may satisfy the Euler-Lagrange equation even when I(Y) is not an extremum. 2019-12-02
follows: expand the original equation to ﬁrst order α and consider a solution of the form z = 1+ λα and put it into the equation, discard all higher order terms α2, α3 and so on and then determine λ. We now show this does not work, why it does not work and how to proceed in this and similar cases. If we use the expansion 1 (1+α)2
