Example 1: Find the first 5 partial sums of the sequence . | ||
NOTE 1: The first 5 partial sums correspond to . | ||
NOTE 2: You will need to nest the series in the first argument of the sequence . Note the use of a different 'dummy' variable, k in the sequence AND that k appears as the upper limit of the series. | ||
Steps | Key Sequence | Screens |
