Hi All,
When copied from another notebook (not mine) the
expression calculates. But when I type in a
version with the exact same appearance, it doesn't
work.
DSolve[{ff^(0,0,0,1)[r,\[THETA],\[PHI],t]==rhs,ff^(0,0,0,1)[0,0,0,0]==Sin[t]},
ff[r,\[THETA],\[PHI],t],{r,\[THETA],\[PHI],t}]
The error msgs are:
Syntax::sntxf: "(" cannot be followed by "0,0,0,1)".
Syntax::tsntxi: "0,0,0,1" is incomplete; more input is needed.
Syntax::sntxi: Incomplete expression; more input is needed .
I've experimented with matching parentheses, but I haven't
been successful so far. What trick am I missing?
