Calculus: An Integrated Approach to Functions and their Rates of Change, Preliminary Edition Part 116. A major complaint of professors teaching calculus is that students don't have the appropriate background to work through the calculus course successfully. This text is targeted directly at this underprepared audience. This is a single-variable (2-semester) calculus text that incorporates a conceptual re-introduction to key precalculus ideas throughout the exposition as appropriate. This is the ideal resource for those schools dealing with poorly prepared students or for schools introducing a slower paced, integrated precalculus/calculus course | Proofs to Accompany Chapter 30 Series 1 1 3 1 n lim n lim a 1 3 x Jx a 1 3 A TO The sequence of partial sums is bounded and increasing. Therefore by the Bounded Increasing Partial Sums Theorem TO 1 a converges. Suppose f x Jx to. Refer to Equation to obtain n 1 x Jx a1 3 a2 3-3 an n Taking the limit as n to gives to lim n. n TO So n grows without bound and TO1 a diverges. Now we show that the behavior of the integral can be determined by that of the series. Because x 0 decreasing and continuous on 1 to lim6 TO f6 x Jx is either flnite or grows without bound. Therefore if we can flnd an upper bound the integral converges. If it has no upper bound it diverges. Suppose TO 1 a converges. Denote its sum by . From Equation we know n J x Jx a1 3 a2 3-3 an 1 n n 1 lim x Jx lim a . nn 1 1 If lim TO n x Jx is bounded so too is lim6 TO f6 x Jx given the hypotheses . Suppose TO 1 a diverges. Because the terms are all positive we know limn TO 1 a to. From Equation we know n a2 3---3 an J x Jx nn lim a lim x Jx. nn 2 We conclude that lim6 TO f6 x Jx to the improper integral diverges.
