Can anybody point me towards a similar problem with a solution. So far in Discrete maths I have had the best results from looking at a problem with a soution and then working out the hows and whys, I have read my notes on this topic over and over but they are long winded explanations in words, with no examples.
So if any one can point me to a similar problem/exercise I would be appreciative. At the moment I seem to be lost with this problem.
, n>= 0 with
(x-9)(x+7) = 0
x=9, x=-7 <---is this part correct?
for arbitrary constants A and B
Mr F says: To check if it's correct, substitute it into the homogenous difference equation. Does it work? (Do you understand the thinking behind what you have done above?)
RHS
64n =
<-- is this correct?? Mr Fantastic is this the particular solution you refer to that should be
Mr F says: Yes. for arbitrary constants A and B
<-- I think my goal is to try and find A and B for these expressions
