Reading Assignment:
  Today (Wednesday) we didn't get as far as expected; we 
    merely completed 6.3 and most of 6.5.
  On Friday we will definately conclude Chapter 6 by covering
    Section 6.4 finishing off 6.5.
  We may also begin Chapter 10.

When reading:
  In section 6.4 just try to understand the examples; the section
    concerns solving differential equations with discontinuous 
    non-homogeneous term.
  The same goes for the second part of 6.5, which deals with 
    impulsive non-homogeneous terms.
