Main Question or Discussion Point
Greetings,
How can I derive the equation satisfied by a rubber sheet? I know that it reduces to Laplace's equation when the sheet is quite planar. I found the expression for it on p.113 in Introduction to Electrodynamics by Griffiths. Thanks in advance.
Edit: I have attached the expression as jpg file.
