Scanned-in pencil-and-paper work.
There was an unfortunate typo in the Julia code used to approximate
the limit which appears in the video. The line which read
n=2&j should have been n=2^j.
Except for getting the wrong answer,
this does not affect the subsequent discussion on how to
create a pdf version of the notebook for upload into WebCampus.
For reference, the corrected files appear below
There were a number of questions asked through chat about Julia and
the computer software we will be using in this class. I have
