Finding the sum of a series is no cakewalk. Sometimes the best we can do is approximate our series with a partial sum. The question is, how far off is our approximation? That's where the Alternating Series Error Bound comes in. Duration: 8:42

In Example 4, we put the Alternating Series Remainder into practice to calculate the error in approximating a series using the sixth partial sum. Duration: 8:03

Finally, in an FRQ environment, we combine both Objectives 1 and 2 to show an alternating series converges, approximate that series with a partial sum, and then show that the error in our approximation is less than 3/1000. That's pretty accurate. Duration: 11:30
