definition of an integral question...
if f(x) ≥ 0, how can you use the definition of an integral to prove that ∫(a,b)f(x)dx ≥ 0?
This seems like it is an easy question, and seems like one of those things that seems obvious but hard to explain, and the only definition of an integral I've been able to find in my textbook is for a definite integral that I didn't find useful.
