General Solution to a Nonhomogeneous System (Variation of Parameters)

This is a video that goes through each step of using variation of parameters to find a particular solution to the nonhomogeneous system, which can then be used with the general solution to the homogeneous system to finally get the general solution to the nonhomogeneous system.
Corrections:
- I believe I said the fundamental matrix is denoted using ξ (Xi/Ksi), but I did mean either Ψ (psi) or Φ (phi)
- Not sure why I mentioned matrix matrix multiplication at the end. Variation of parameters here only uses matrix vector multiplication for the most part. Undetermined coefficients makes use of matrix matrix multiplication
