10.5 The Ratio, Root, and Comparison Test Math 6B Calculus II
The Ratio Test Then a) the series converges if r < 1. b) the series diverges if r > 1. c) the test is inconclusive if r = 1.
The Root Test Then a) the series converges if r < 1. b) the series diverges if r > 1. c) the test is inconclusive if r = 1
The Comparison Test(a.k.a – Direct Comparison Test) • Suppose that and are series with positive terms.
The Limit Comparison Test • If L = 0 then converges, then converges. • If L = and diverges, then diverges.
