Lecture 24: Laplace’s Equation

(1) These equations are second order because they have at most 2nd partial derivatives (2) These equations are all linear so that a linear combination of solutions is again a solution 24 2 Steady state solutions in higher dimensions Laplace’s Equation arises as a steady state problem for the Heat or Wave Equations that do not vary with time
