Comment (by kcrisman):
Okay, I like your patch. I do think that there should be support for
{{{
sage: f(x)=x
sage: integrate(f,-1,1)
0
}}}
I wasn't suggesting integrating a symbolic equation, just that the same
behavior results for
{{{
sage: integrate(f,-1,1)
0
sage: integrate(x,-1,1)
0
}}}
because I don't think most newbie Sage users will get the difference
between f(x)=x and f=x, for instance.
Anyway, the latest patch applies the appropriate parts of your patch to
CallableSymbolicExpression as well; there needs to be less checking
because of the different return expected, e.g. indefinite integral is
already handled by the previous code (still returning a
CallableSymbolicExpression, though).
Unfortunately, calculus.py always times out for me when I test it. I
tried to check that I did not change any existing behavior but hopefully
you (or someone else) can check this.
Otherwise positive review!
