Therefore, the equation is,
dU
+ ka? U (a, t) = 0
dt
The particular solution of the above equation,
U (a, t) = ce¬ka²i.
(2)
At the given boundary condition and use the given identity,
F {u (x, 0)} = F {ex*}
So, the above equation is expressed as,
U (α, 0)
Vñe .
(3)
Substitute t =
O in equation (2),
U α, 0)
(4)
= C.
Equate the equations (3) and (4),
c = Vãe?
