Hey-lo everybody,
I am having trouble finding information on solving difference equations with the "iteration method."
The Q: was solve the following difference equation
y(k+2) + y(k+1) + yk = 0 where y0 = 0, and y1 = 1
I got y0=0, y1=1, y2=-1, y3=0, y4=1, y5=-1, y6=0 ...
or {0,1,-1,0,1,-1,0,...}
I don't know what to do from here, and my text has nothing on the "Iteration method." I've searched the net, and the search results were either books I had to pay for, articles I had to pay for, or simply much more info than I need.
If anyone can tell me where I go from here, I would appreciate it. I'll be taking signal processing next semester, and I would like to get this stuff "down pat" before then.
Thanks,

P.S. Yes, this is homework. But I will be happy if you can just give an example.
