I have what should be a very simple problem, but I can't convince
Mathematica to give me an answer in the form that I need. I have sets
of equations like
{x[t] == y'[t], y[t] == 5}
that I would like to solve. If I try the obvious
DSolve[{x[t] == y'[t], y[t] == 5},x[t],t]
I get
Out[14]=
{{x[t] -> y'[t]}}
as the result. I would like, of course, to see {{x[t] -> 0}}. How can I
get Mathematica to give me this answer?
The equations are being generated automatically, and Mathematica is being
called remotely. The solution should be in the form of a single
self-contained request with no side-effects.
Many thanks for your help,
Adam
