- Another homework due today: pp. 89--, #1, 4, 5, 8, 13
- One homework returned (p. 68); I'm still holding your p. 78 assignment -- sorry!
- On #1: don't give up too soon! As we see in #3, a derivative may exist only along a line!
- #2: Remember to check continuity of partials for derivatives to exist.
- #6: use the limit definition at 0
- Test: Monday, 3/22
- Today's activity, and new assignment:
Mon 3/15 83-86 - Read 88 and 89
- We're jumping now to Chapter 8 (Mapping by Elementary Functions), on our way to conformal mapping. Read sections 83-85 (should go quickly -- we've already seen much of this); we'll review that, then jump into section 86 (mobius transformation)
- Problems: to come....
- Linear (Affine) Transformation
-
-
maps circles and lines to circles and lines
- Mobius transformations
