Homework Equations
[tex]\nabla[/tex][tex]^{}2[/tex]V=0
Seperation of variables: V(x,y)=X(x)Y(y)
The Attempt at a Solution
For simplicity I divide problem into two parts:
1st part- Click the link below: potential_problem_part1.jpg
I tried to use separation of variables, yet, didn't decide which one would be sin(kx),cos(kx) and exp([tex]\pm[/tex]kx).
Here is another problem : There is no way to determine "k",and thus use sum of "fourier sine series".
2nd part- Click the link below: potential_problem_part2.jpg
The potential at x=0 is a step function i.e
[tex] V(x=0,y) =\left\{\begin{array}{cc}0,&\mbox{ if }x<0\\V_{0} , & \mbox{ if } x>0\end{array}\right[/tex]
so, how to find the functions for this boundary?
