Duhamel's Principle is a technique used in solving linear inhomogeneous partial differential equations by expressing the solution as a convolution of the system's response to initial conditions and the forcing term. It leverages the idea that the response of a linear system to an external force can be constructed by integrating the effects of that force over time, thus relating it to the fundamental solution of the associated homogeneous problem. This principle is particularly useful in applying Laplace transforms to facilitate solutions for complex systems.
congrats on reading the definition of Duhamel's Principle. now let's actually learn it.
