In part (c) of this problem you will have to use as input , and find the steady state system response. The correct general formula which you should prove is as follows:

Hint: assume that .

You can therefore find the solution in the required form by using the Euler formulas: use and express the general solution of the difference equation as (you need to figure out this exponent!).
