How can you specify an integral with a constant integrand? For example, I know that
f = x
f.integrate(x,0,1)
works fine, but
f = 1
f.integrate(x,0,1)
doesn't, since the Integer class has no integrate() method. (Should it?) I can get around this with something like
f = x-x+1
f.integrate(x,0,1)
but that seems awfully kludgey.
