Getting Homework 1 solutions

You should be able to download Homework 1 solutions (in pdf version of “written” solutions) , and an alternate version of those solutions using Mathematica (in a notebook file) from the math421-murray UDrive. That course UDrive should have sent you an e-mail containing a link to its “Homework solutions” folder.

As an expedient, in case you are having trouble with that, I’ve put direct links to the files on the Homework page of this course web site.

Revised & new notebooks available

Several of the Mathematica notebook files previously posted to the Files page have been updated with revised versions. These include:

• DrawingComplexObjects.nb—a major revision.

New notebooks are:

• VisualizingFunctions.nb
• CalculatingImages.nb

Homework 2

Homework 2 is due Friday 24 September at the start of class, except that question #1 consists of the two problems from WeBWorK set 421HW2, which is due Thursday 23 September 5:00 p.m.

See the Homework page for a link to the Homework 1 assignment, in the form of an Adobe pdf file.

WeBWorK is now available

You are now rostered in the on-line WeBWorK homework system, and the first work there is available to you.

Homework 1!

Homework 1 is due Monday 20 September at the start of class, except that question #1 consists of the work from WeBWorK set 421HW1 and that WeBWorK part is due Sunday 19 September 5:00 p.m.

See the Homework page for a link to the Homework 1 assignment, in the form of an Adobe pdf file.

Note: WeBWorK Problem 5 does not recognize the “sqrt” function notation. It seems to require that you enter your answers using (…)^(1/2) notation for square-roots of (positive) real numbers. Or, instead, you can use decimals rather than exact expressions involving square-roots at all.

Math Club meets Wed 9/15

The first meeting for the semester of the Math Club will be:

Wednesday 15 September
6:00–7:00 p.m.
LGRT 1521D
Pizza will be served (as usual)

This will be a “game night”.  And the Club’s leaders will show  new students what the Math Club has to offer and to tell them about some of the talks and activities we have planned this semester.

This is a great opportunity to meet other students interested in math, including Math Majors.

Welcome to Math 421!

This web site is intended for students in Prof. Murray Eisenberg’s Fall 2010 Math 421, Complex Variables.

Math 421 meets MWF 10:10–11:00 p.m. in LGRT 219

Exception: on Friday September 10 and Monday 13 September the class meets  in the Math & Stat Resource Center, LGRT 110.

• Bring a USB “thumb drive” (flash drive) those days, if at all possible, or be prepared to upload to your UMass OIT UDrive (or other drop-box).

Information about the required textbook appears on the Textbook page. Complete information about the course—software to be used, exams, homework, and other requirements; syllabus; etc.—appears on the About page.

Finding this web site

If you forget the URL…

• go to `http://www.math.umass.edu`
• click the Courses link and select Course Webpages from the fly-out menu
• click the Math 421 link on the Course Webpages page.

You should try to do so in the normal way—through Spire. Due to constraints on grading time and limited seating in labs where our class will meet at some times, I cannot exceed the capacity.
