4-types

1) Determine whether convg or divg AC,CC 2) Find the sum s

4) How many terms are needed

within error

Types of questions in the exam

5) Partial sums and their properties

PART-1: Series with positive terms

1) Divg Test

2) factorial: ratio test comp+lim comp

3) power of n: root test

4) easy to integrate: integral test

5) similar to geometric: try comp+lim comp

6) Similar to p-series: try comp+lim comp
