Homework Statement
X(x)=(Ae^kx+Be^-kx)
Y(y)=(Csin(ky)+D(cos(ky))
V(x,y)=(Ae^kx+Be^-kx)(Csin(ky)+D(cos(ky))
Homework Equations
separation of variables
The Attempt at a Solution
so our boundary condition says that as x->infinity , V=0
this is only possible if A=0
so A=0 and Be^-kx= 0
so X= Be^-kx
and
V(x,y)=(e^-kx)(Csin(ky)+D(cos(ky))
why is there an e^-kx on the front. Shouldn't there also be a B?
