A change of branch is recommended.) - (3/15) Study guide for MT3. There are two main themes for this exam:

1. You will need to know how to find the Taylor / Maclaurin series of the common elementary functions, like exponential functions, sin and cos etc. For example, review Examples 1, 2, 4, 5 in Section 59 and exercises within.

2. Application of the Cauchy--Goursat Theorem and integral formula. For example, review exercises in Sections 45, 49, 52.

questions and go over a few problems I personally picked,
(as many as the time allows.)
Remember to bring your HW due on 25th to the class.
Next
**Thursday (27th) is the first midterm exam!**There are**5**problems in the test, so you have only about 10 minutes for each problem.**All**problems come from your HW. So work on all your HW problems, without notes and books, would be a great way of preparing for the test. Also come in early and bring your student ID card. The exam will start 5 minutes before the bell time and Feng might check your ID card. - (1/14) Some comments on HW Section 10 #2-4:
You will need to
**1.**Find the roots (plural!)**2.**Write them in rectangular coordinates.**3.**Put them in graphs like Figure 13. Note though #2(b) will not be "symmetric."**4.**Point out which root is the principal root. That is, the angle is less or equal to \pi, but greater than - \pi. - (1/13) A student asked about the significance of | z - (1 + i 2) | < = 3 and the likes. A simple calculation will show that it is the same as (x-1)^2 + (y-2)^2 < = 3^2. This means exactly all points on the complex plane whose distance from (1,2) are less or equal to 3.
