The first one I got the solution:
Dear all, the following ar Berkely problem (Spring 85).
Let be given. Consider the linear difference equation
(Note the analogy with the differential equation .)
- Find the general solution of by trying suitable exponential substitutions.
- Find the solution with and . Denote it by ,
- Let be fixed and . Show that
2. I find that
3. I then confused then. Since I could only verify that
In my calculations, it seems to be \infty. What's going wrong?
Would you help me? Thank you.
