I wanted to solve a differential equation via DSolve. When naming the
constants with subscripts (e.g. for the mass of the sun M_Sun with the
word Sun on the line), Mathematica 5 in some way misinterpreted this
and told me:
DSolve::bvfail : For some branches of the general solution, unable
to solve the conditions.
It works, when I leave out the subscripts and name the mass of the sun
simply M and the mass of a planet m, but for optical reasons it would
be nice to have subscripts for better understanding.
I also tried this with Mathematica 4.2 in university - and it worked
fine, but I only have version 5 in my office.
In help files it is said, that Mathematica wouldn't interprete
subscipts in any other way than as names, but obviously it does...
Is there any point in preferences to tell the programm how it should
handle these things?
I'm grateful for any help
