Webagainst the boundary conditions. To obtain the solution (1.4) , the PDE was first solved regardless of the boundary condition: Next, the arbitrary function was determined such that the boundary condition is matched. Concretely, the mapping _F1 is what was determined. You can see this mapping reversing the solving process in two steps. WebIf the initial conditions satisfy the boundary conditions (as they should) then all that is needed to to make sure that the time-derivative (the change with time) of the boundary points is always zero.
