Há 5 dias · Helmholtz equation. We demonstrate application of the separation of variables in solving the Helmholtz equation ∇2u + k2u = 0. The Helmholtz equation often arises in the study of physical problems involving partial differential equations (PDEs) in both space and time.
Há 5 dias · We solve the given problem numerically: ode := diff(y(x), x, x, x) + x*diff(y(x), x)^2 = 0. bics := y(0) = 1, D(y)(0) = -2, y(1) = 1. answer := dsolve({bics, ode}, numeric) answer:= proc(x\underscore bvp)... endproc answer := p r o c ( x \underscore b v p)... e n d p r o c. The output of dsolve is by default a Maple procedure of a single argument.
Há 6 dias · In mathematical optimization, the method of Lagrange multipliers is a strategy for finding the local maxima and minima of a function subject to equation constraints (i.e., subject to the condition that one or more equations have to be satisfied exactly by the chosen values of the variables).
