HW …. • WebAssign 11.4
Bonus Event (5/9) • Your feedback is very helpful to the speaker.
Bonus Event • Friday 5/23; 5:10- 5:40 (Hedging), 5:45-6:15 • You will get 2 points for the first presentation and 1 point for the second one. • If you participated in the 5/9 event, you will get an additional bonus point for attending both presentations. • You are not eligible to sign up if you signed up but did not show up last time. However, stand-by is welcome if seats are available.
Reminder to Wai • Do the first 3 examples on the board without erasing • Overwrite on the first 3 examples to save time
Preview • Comparison Test • Limit Comparison Test • Only work for series with positive terms • Compare with standard series • The nature of the comparison is term-by-term

The Comparison Test Suppose for all . If is convergent then is also convergent If is divergent then is also divergent
Be Careful!!!!! Suppose for all . If is convergent then is also convergent However, If is convergent then there isno conclusion for
Series to compare with • Geometric Series • Harmonic Series • -series
Remarks For convenience, we will call the following series a p-series. It has the same convergence as
Series to compare with • Geometric Series • Harmonic Series • -series
Example 1 • Write down the general terms of the two series • Write down the comparison and range • Find the convergence of the comparison series • Make the conclusion by quoting the name of the comparison test
Common Mistake/Misconception Comparing the series instead of comparing the terms STOP The series are not comparable unless you first show that they are both convergent. The comparison test is based on the comparison of general terms.
