In Mathematica 5.0, if one types in:

f[x_]+g[x_]^:=1

dx(f[x]+g[x])

we get 0.

However, if we type dx(f[x]) + dx(g[x]), we get

f'[x] + g'[x].

Mathematica doesn't recognize that f'[x]+g'[x]=
(f[x]+g[x])', which equals 0. How does one get Mathematica to do this?

I'm interested in situations where f'[x] and g'[x] occur within a larger equation.

Are there any resources on utilizing Mathematica to manipulate Partial Differential Relations?

Thanks,
Sunil
