Hi All,
1) The recommended exercises file has been posted in the course page, under "Resources". The file will be updated regularly in the future.
2) You may notice a few discrepancies in the equation numbers between my whiteboard writing (which were based on an older edition) and the newer version of the ESL book that you can download on the course page. However, you should be able to locate the equations easily in the book since the same notation is used.
Best,
Chun
