Let > an be a series with nonzero terms. n=1 For the RATIO TEST, define p = lim an+1 For the ROOT TEST, define p = lim Van. n-+00 an (1) If 0 S p 1 or p = oo then Can diverges. n=1 (3) If p = 1, then the ratio test is inconclusive. In problems 1-, apply the ratio or root test and state whether the series is convergent or divergent. 4. (2n)! n=1 5. Cenn! i8 i 10" 6. (n + 1)42n+1
