Math 641600 Midterm Review
The midterm will consist of an inclass part, which will be given on
Wednesday, Oct. 14, and a takehome part. It will cover sections
1.11.4, 2.1, 2.2.12.2.3. It will also cover the material done in
class and covered in my notes, starting with "Adjoints,..." and ending
with "Pointwise convergence of Fourier series." See Class notes on my web page.
The inclass part of the midterm will consist of the following:
statements of theorems and definitions; short problems or propositions
similar
to homework
problems or examples done in class; and either a critical part or
sketch of a proof for one of the major theorems proved.
The takehome test will have longer computations, proofs, or
problems. It is due on Monday, October 19, at 4 pm. You may bring the
test to me directly (Blocker 611D) or put it in my mailbox on the
second floor.
