Differential Equations Superposition Principle and Undetermined Coefficients

Cochise College MAT 262 lecture for 10/11/2023. In this lesson we discuss how to combine solutions of a complementary homogeneous system with a particular solution to a nonhomogeneous DE. In order to do so, we need to be able to find such a particular solution, which we do by guessing the form of the solution and computing the details.
