Math 641-600 (Fall 2014) — Final Exam Review
The final will be given from 8 am to 10 am on Tuesday, December 16,
2014, in our usual classroom. The test will cover sections 2.2.3,
2.2.7, 3.2-3.6, 4.1, 4.2 4.3.1-4.3.2 (2nd order operators, only), 4.5
(pp. 161-163) in the
text, class notes, and
any material covered in class. The test will be composed of two
parts. The first part will consist of statements of theorems and
definitions; the second will have short problems or propositions
similar
to homework
problems or examples done in class, as well as a proof of one of
the major theorems highlighted
in blue below.
