MATH 106 Final Exam Review, Part II

  1. Find the solution to dy dx = cos y 2 x that passes through (0, 2).
  2. Use a second-degree Taylor polynomial to estimate โˆš^3 28.
  3. What is the largest possible error that could have occurred in your previous estimate?
  4. Use a comparison to show whether each of the following converges or diverges. If an integral converges, give a good upper bound for its value. (a)

(b)

  1. Decide if each of the following sequencesverges, compute its limit. {ak}โˆž k=1 converges or diverges. If a sequence con-

(a) ak = 3 + (^101) k (b) ak = (โˆ’1)k (c) ak = 3 + 5 7 + 2kk

  1. Circle the appropriate word to complete each of the following statements correctly.

(a) If the individual terms of a series approach 0 ( lim nโ†’โˆž an = 0), then the series nโˆ‘^ โˆž=1 an will converge (always/sometimes/never). (b) If the individual terms of a series approach 0.5 ( lim nโ†’โˆž an = 0.5), then the series nโˆ‘^ โˆž=1 an will converge (always/sometimes/never). (c) If the individual terms of an alternating series approach 0 ( lim nโ†’โˆž an = 0.5), then the series nโˆ‘^ โˆž=1 an will converge (always/sometimes/never). (d) If the individual terms of a geometric series approach 0 ( lim โˆž nโ†’โˆž an = 0), then the series โˆ‘ n=1^ an^ will converge (always/sometimes/never). (e) If the ratio of the terms of a series approaches 1 ( lim nโ†’โˆž^ an a+1n = 1), then the series nโˆ‘^ โˆž=1 an will converge (always/sometimes/never). (f) If the ratio of the terms of a series approaches 0.5 ( lim nโ†’โˆž^ a an+1n = 0.5), then the series โˆ‘^ โˆž n=1^ an^ will converge (always/sometimes/never). (g) If a series has all positive terms, then it will converge to 0 (always/sometimes/never).

  1. Decide if each of the following series converges or diverges. If a series converges, find its value. (a) 3.1 + 3.01 + 3.001 + 3.0001 + ... (b) 1 + 1/2 + 1/3 + 1/4 + ... (c) 5 โˆ’ 5 /3 + 5/ 9 โˆ’ 5 /27 + ...
  1. Compute the radius and interval (including endpoints) of convergence for nโˆ‘^ โˆž=1^ (x n^ + 3) ยท 5 n n.
  2. Find the complete Taylor series (in summation notation) forand determine its interval of convergence. f (x) = ln (1 โˆ’ x) about x = 0
  3. Write the complete series equal to

โˆซ (^1) 0 eโˆ’x

(^2) dx and show that it converges.
