Why Use the Reflection Principle for Boundary Conditions in PDEs?

Winzer · May 8, 2009

Can someone explain to me why do we use this for boundary conditions in the heat, and wave equations? Why must we make an odd extension of our initial data and not even?

Probably because integration of an odd function is zero.

[tex]\int_{-a}^a f(x) dx = 0[/tex]
