Class of 11\/30 basically talked about different Theorem related to the Properties of Integral. Those Theorem are built around the Fundamental Theorem of Calculus which we will discuss in next class meeting.<\/p>\n

We talked about Theorem 7.4.1 which states that\u00a0Assume \"f is bounded, and let \"c. Then, f is integrable on [a, b] if and only if f is integrable on [a, c] and [c, b]. In this case, we have \"\int_a^b. The proof of this theorem uses the definition of refining a partition and the proving techniques of the Riemann integral.<\/p>\n

 <\/p>\n

Then we introduces Theorem 7.4.2 which catalogs the basic properties of integral.<\/p>\n

Theorem 7.4.2\u00a0Assume f and g are integrable functions on the interval [a, b].<\/p>\n

1).\u00a0The function f + g is integrable on [a, b] with \"\int^b_a.<\/p>\n

2).\u00a0For \"k, the function kf is integrable with \"\int^b_a.<\/p>\n

3).If \"m on [a, b], then m(b \u2212 a) \"\leqM(b \u2212 a).<\/p>\n

4).\u00a0If \"f(x) on [a, b], then \"\int^b_a.<\/p>\n

5.The function \"|f|\" is integrable and \"|.<\/p>\n

 <\/p>\n

The proof of (2) requires an extra attention that we need two cases where k can be positive or negative. If k is positive, then for any partition P we have \"U(kf,P) and \"L(kf,P). And since f is integrable, there exists partition \"(P_n)\" and consider function \"(kf)\". We have \"\lim\limits_{n [U(kf, P_n) \u2212 L(kf, P_n)] = \"\lim\limits_{n k[U(f,P_n) \u2212 L(f,P_n)] = 0. And if k is negative then\u00a0we have \"U(kf,P) and \"L(kf,P).<\/p>\n","protected":false},"excerpt":{"rendered":"
