1 | The term H is to viewed as an external force so arranged that a simple function exactly satisfies equations |
2 | The simple function is a linear combination of powers ( 0 through 4 ) of x h and z. |
3 | The boundary conditions and initial conditions are similarily set to have a very simple form |
4 | Note H does not depend on the unknown U in spite of what memo says! |
5 | H depends only on independent variables x h and z. |
