An updated and extended version ¡­

An updated and extended version of the Exercises file has been uploaded; please print out the appropriate Exercises, update D, now comprising 30 pages and a total of 32 exercises.

Exercises for Wed Nov 14 are as indicated in the previous message, but since the "Update D" is now available I redefine the homework assignment to be Exercises 18(e), 20, 21, 22, 23.

It is also advisable to read through all remaining exercises, as the course curriculum will include (nearly) all of them.
