I need to show that the solution of
a_n = c_1a_{n-1} + c_2a_{n-2} + f(n) (1)
is of the form
U_n = V_n + g(n) (2)
where V_n is the solution of a 2. order linear homogenous recurrence relation with constant coefficients.
Could I use the argument that if (2) is a solution...
Hallo everybody.
I have a square matrix where the coefficients of the diagonal are 1, while the others are very small (say 10^-6). Of course the determinant of this matrix will be always one.
This is my problem:
the coefficients are functions of a variable (w, complex variable). So, the...
