Integrate with explicit integration variable/infetesimal...



Is it possible to get Maxima to automatically integrate expressions of 
this form:

	f(i) := (i*di - c);

That is, a function like integrate that takes three parameters:

	xintegrate( f(i), i, di );

Obviously the above case is trivial, but in my equation I can't easily 
separate out the di term in order to pass the function to integrate (I 
have an expression in the form of a sum right now, but I want to create 
the integral instead).
