I just realized I can do subscripts. The original problem is this:
xt+2-3xt+1+2xt=3(5t)+sin(0.5πt)
Yeah it's a difference equation so we only have discrete moments of time.
Homework Statement
Find the general solution
Homework Equations
x(t+2)-3x(t+1)+2x(t)=3*5^t+sin(0.5πt)
The Attempt at a Solution
I start out by solving the homogeneous equation and end up with the two roots 1 and 2.
Then I try to use the method of undetermined coefficients to find a...
