Hi there,
I arrived at the solution for a electric potential problem for a semi-infinite cylinder (there was a potential distribution given for the boundary conditions but that's not important here).

The solution is equation (1). You have to use the Bessel functions of first order and there is a parameter λn appearing (equation (2)). My problem is how to calculate the various λn values. I know it must work with an iterative procedure. I am especially interested in a Mathematica procedure to do this.
Thanks in advance for some helpful hints,
OMN
