Math 120B, DUE DATES 2015
Weds, April 8
Ch 5 Churchill has done by in M120A by all but a few students in the class.
So unfortunately students who have not seen it will need to put a lot of work
in early to become familiar with it. I will hit the high points of Ch 5
in class. Even if you saw it before the topics
I emphasize might be new to you and (likely) one will not be in the book.
Our TA agreed to give a lecture
on the topic (Laurant expansions) in section this weds.
Here is a list of HW exercises,'
carefully pruned down to the essentials.
Sec 61 2, 3
Sec 69 (very important)
Let
g(z)=(z - 2) (z-3) and let f(z) = p(z)/g(z) where p is a polynomial.
What is the radius of convergence of the power series expansion
about z_0 = i? (Hint you do not need to compute the expansion)

Ch 6
Sec 84
What type of singularity does f(z) = e^{- 1/z^2} have at 0?
What are all solutions to f(z) = e?
Partial Fraction Expansions: What form does the partial fraction
expansion have for the functions f_j below.
f_1(z) = z^3/(z-4)(z-2)^2
f_2(z) = z/(z-3)(z-2)
Prove it (as was done in class).
You do not need to compute the coefficients precisely.
