Proposition: Properties of the Riemann Integral

Suppose f is a Riemann integrable function defined on [a, b]. Then

• c f(x) + d g(x) dx = c f(x) dx + d g(x) dx
• If a then f(x) dx = f(x) dx + f(x) dx
• | f(x) dx | | f(x) | dx
• If g is another function defined on [a, b] such that g(x) on [a, b], then g(x) dx f(x) dx
• If g is another Riemann integrable function on [a, b] then f(x) ^. g(x) is integrable on [a, b]
