WebNov 16, 2024 · In this section we’ll define boundary conditions (as opposed to initial conditions which we should already be familiar with at this point) and the boundary value problem. We will also work a few examples illustrating some of the interesting differences in using boundary values instead of initial conditions in solving differential equations. WebThe boundary conditions in a problem define how a solution to a differential equation behaves at the boundary of a system. Boundary conditions can be fixed values or they can be defined as some other function in space and time.
