All material we cover in Chapters 1--3 including this week: namely, from Chapter 3 linear homogeneous equations with simple real roots (3.2), double real roots (3.4), complex roots (3.3) and also inhomogeneous equations with quasi polynomial right hand expressions (3.5) and method of variations of parameters. There could be Euler equation (problem 34 on p 166).

There are three handouts

* Handout 4b--to section 3.5 (Euler equations).

* Handout 4c--to section 3.6 (Summarizing Method of Variation of Parameters, section 3.6).

Also material we covered in Chapters 1, 2.
