The solutions, d1(µ) and A2(u), of this equation are d1(14) = H, A2(µ) = µg/p. (5.93) This gives the following two particular solutions: 21(k, l) = µk+e and 22(k, l) = (q/p)*µk+e_ (5.94)

Show me the steps of determine green

5.3.3 Example C
Let p+ q = 1 in the equation
z(k, l) = pz(k + 1, l – 1) + qz(k – 1, l+ 1).
(5.91)
Lagrange's method requires that
pX² – µd + q²µ² = 0.
(5.92)
The solutions, d1(1) and A2(u), of this equation are
= l, A2 (u) = µq/p.
(5.93)
This gives the following two particular solutions:
C:1(k, e) = k+t and 2(k,() = (9/p)*p*+*
and 22 (k, l) = (q/p)*µk+e,
(5.94)

Difference Eq
ions
Summing these expressions and adding the results gives the general solution
2(k, l) = g(k+ l)+ (q/p)*h(k+l).
(5.95)
Note that the separation-of-variables method does not work for this
tion, since if z(k, l) = CkDe, the following result is obtained:
equa-
Ck De = pCk+1De-1+ qCk-1De+1;
(5.96)
and the necessary separation into expressions that depend only on k and l
cannot be done.
