Show me the steps of determine red and it complete

8.7.3
Example C
For the equation
Ay(x) = Dy(x),
(8.282)
it follows that
C
y(x + 1) – y(x) =
dx
dy(x)
(8.283)
This is a linear equation, with constant coefficients, and we will assume the
solution takes the form
y(x) = e"ª,
(8.284)
and, therefore, we find
dy(x)
y(x + 1) = e"(2+1) = e"e"ª,
re"*.
(8.285)
dx
Substitution of these results into the original equation and canceling the com-
mon factor e"", gives the transcendental equation
e" - r – 1 = 0.

Difference Equations
Note that this equation has solutions in terms of the Lambert W-function. In
general, an infinite set of roots exist and if they are denoted by {rm}mE,
|m=∞
then the solution takes the form
Cy(2) = E ame"mz,
(8.287)
rmx
m=0
where {am} are constants. Inspection of equation (8.286) shows that r
a solution, thus one solution to Ay(x) = Dy(x) is y(x) = A, where A is an
arbitrary constant.
