I have been signed off of Mathgroup for a couple of years, but I was just
asked a question I couldn't answer... so I'm back! I went through the
recent archives on the wolfram web site and couldn't find an answer. I
hope this doesn't cover old ground, but...
given an equation and the need to apply some rule for algebraic
simplification, can you get Mma to apply that rule to just a specific term
of the equation?
f[x] g[x] + (f[x] g[x] + 1) == Sin[x] + 2
can we write a rule to factor out g[x] only the second term to give:
f[x] g[x] + g[x](f[x] + 1/g[x]) == Sin[x] + 2
This may seem odd, but my colleague is quite adamant about wanting to
control the form of her equation, term by term. I had to confess that I
had no idea how to work with just part of an equation, and the book didn't
offer and insight.
I'll appreciate any help anyone can offer-
