1 Section 8: Alternating Series

2 A series in which the terms alternate sign.
Alternating Series: A series in which the terms alternate sign.

3 The Alternating Series Test
Series converges if: Alternates Terms decrease in magnitude Terms approach zero

4 Ex 1: converge or diverge? A) B)

5 Ex 1: converge or diverge? C) D)

6 Alternating Series Error Bound:

7 Ex 2: Use S5 to give bounds for the value of:

8 Ex 3: Using the alternating series bound, what degree Maclaurin polynomial is required to estimate cos(3) with an error of no more than 0.001?

9 If converges, then is Absolutely Convergent.
If diverges and converges, then is Conditionally Convergent.

10 Ex 4: Absolutely Convergent, Conditionally Convergent or Divergent. A)
Ex 4: Absolutely Convergent, Conditionally Convergent or Divergent? A) B)

11 Ex 4: Absolutely Convergent, Conditionally Convergent or Divergent? C)

12 Ex 5: Find the Interval of convergence:
