Goal: we will prove that if f and g are two Riemann integrable functions then ?ab?(f(x)+g(x))dx=?ab?f(x)dx+?ab?g(x)dx. First, we will prove first that f+g is Riemann integrable and then prove the above equality. 2.1 Show that ?P partition of [a,b],U(f+g,P)?L(f+g,P)?[U(f,P)?L(f,P)]+[U(g,P)?L(g,P)]. 2.2 Using 2.1 and the definition of Riemann integrability, prove that f+g is Riemann integrable.
Using the property that a Riemann integral can be written as the limit of a Riemann sum, prove that ?ab?(f(x)+g(x))dx=?ab?f(x)dx+?ab?g(x)dx.
