Example 1. Identify 2. 3. Conditionally Converges
Conditionally Convergent Series is conditionally convergent if converges but diverges
Example 1. Identify 2. 3. Converges
Example Converges Converges ABSOLUTELY CONVERGENT

Approximation Given a convergent alternating series, is the sum of the series, is the nth partial sum, Then Error in approximating the entire sum with the
Theorem If a convergent alternating series satisfies the condition , then the absolute value of the remainder
