Why do some inputs in The Skin Effect section of F TransmissionLines evaluate to incorrect answers in Mathematica 4.1 and later?
 There was a design change to DSolve in Mathematica 4.1 which requires some changes to the input cells in F TransmissonLines Skin Depth in order for all evaluations to return correct answers. The constants C[1] and C[2] have been reversed. To correct the inputs, you will need to do the following: | 1. | Open the Help Browser and select . |
| 3. | Scroll down to and change the following line from: |
| 4. | At , change the following line from: |
While the form of output will differ slightly, evalutions in will now return correct answers. In particular, the plots will generate without error and the code below: will now return instead of 0.  Download this FAQ as a Mathematica 5.2 Notebook
