1. 12-3 Infinite Sequences and Series

5. Hints to solve limits: 1)Rewrite fraction as sum of multiple fractions Hint: anytime you have a number on top, and variable on bottom, the limit is 0. (ex 1/x 2, 1/x 3, 4/5x 2) Anytime you have a variable on top (2x, 3x, x/2) the limit is ∞, or Does Not Exist

6. Practice:

11. Convergent Series: An infinite series that approaches a limit Divergent Series: An infinite series that does not approach a limit. All arithmetic series are divergent In a geometric series, if lrl > 1, the series is divergent if lrl <1, the series is convergent

13. Add the following: 4 +.001 +.0001 +.00001 +.000001

15. 7)Find the sum of the series: 21 - 3 + 3/7-… 8) Find the sum of (6/5) + (4/5) + (8/15)+…
