WebJSTOR Home WebNote that the case L=0 is simply the fundamental theorem of calculus, indeed one can view Duhamel's formula as the fundamental theorem of calculus twisted (conjugated) by the free propagator . For equations which are second order in time, the formula is slightly more complicated. For instance, the solution to the inhomogeneous initial value problem
