New issue 3955 by [email protected]: sympy.Function.replace with the
together() method
http://code.google.com/p/sympy/issues/detail?id=3955
Say I have y = exp(-x/2 + 1) + 1
and I do:
a = Wild('a')
y = y.replace(exp(a), exp(a.together()))
I would hope to get
y = exp((-x + 2)/2) + 1
but instead I get the original y = exp(-x/2 + 1) + 1
I don't know if this is intended - because if it isn't then to do the same
thing you'd have to do a lot more work using match (depending on the
complexity of the function you're matching on)
