Hi folks,
I get an findroot error message which gives no clue (at least to me) to
correct the my statement
(FindRoot[2 Pi - Phi[x]== PhiC[0, x]+ 2 Kappa[x]*(zc - zb), {x, 4} ]
FindRoot::"frnum":
"Function (3.69495079385213065` - 1. (ArcTan[(0.692041522491349425]
(<<1>>) is not a length (1) list of numbers at {x} = {4.`}
Sorry not easy readable, but i can send an attachment if it is wanted in
a newsgroup.
I'm happy for any useful hint.
