| Title | Summary |
|---|---|
| Second-Order Linear Equations: Variation of Parameters | Paul's On-Line Notes on the method of variation of parameters for solving
second-order nonhomogeneous linear equations. They apply this method to equations with constant coefficients when the forcing does not have characteristic form and to equations with variable coefficients when a general solution of the associated homogeneous equation is given. The first case generally is treated faster by the constant coefficient Green function method, which is not covered by in Paul's notes. |
| Higher-Order Linear Equations: Variation of Parameters | Paul's On-Line Notes on the method of variation of parameters for solving
higher-order nonhomogeneous linear equations. They apply this method to equations with constant coefficients when the forcing does not have characteristic form and to equations with variable coefficients when a general solution of the associated homogeneous equation is given. The only example given is treated faster by Key Identity evaluations or Undetermined coefficients. |
