                            Discussion 3

1)  Discuss the roles of the following concepts in solving recurrence
    relations (Part A).

    a) characteristic equation
    b) characteristic root
    c) general solution
    d) specific solution
    e) particular solution

2) Identify which of these concepts depend on each other and how.  An example
   would be to explain how the characteristic roots are used to create the
   general solution (Part A).

3) Each of you creates and solves a linear homogeneous and a linear 
   inhomogeneous recurrence relation. You should then announce the problem
   (not the solution) to the group (Part A).  Be sure the coefficients of
   your recurrence relations are positive to avoid the problems discussed 
   in class.

4) Agree which group member is going to solve each of the problems 
   presented by one of your peers (not the one that presented it).  This means
   everyone gets 1 linear homogenous and 1 linear inhomogeneous problem
   to solve.  Those that created the problem are on their honor not to 
   disclose the solution until Part C. (Part B)

5) Each of you solves the problems you took on and posts your solution to the
   group.  (Part B).

6) All discuss and agree on all definitions and solutions.  This should 
   be presented as your final report. (Part C)
