Reading Assignment:
  Today (Monday) we covered most of Section 6.3.
  On Wednesday we will finish 6.3, begin 6.5 as explained
    in the previous assignment.
  We will also cover most of 6.4, time permitting.
  You should finish reading 6.5 & 6.4 to prepare.

When reading:
  Since 6.3 and the beginning of 6.5 were addressed in the
      previous homework I won't say anything more about them 
      here.
  For the remainder of 6.5 and all of 6.4 there's not much 
      additional going on; just extending the method of solving
      differential equations using Laplace Transform to the
      cases of discontinuous and impulsive non-homogeneous terms.
  Just try to understand the examples.

Problems (due Friday, 2/27)
  Section 6.3 : 1,4,8,9,11,14,15,17,19a
