Homework
Math 20C Winter 2014
Lecture C


The homework will account for 15% of your grade.
It will be assigned (more or less) weekly, to be submitted by 11:59pm on the due date (generally on Fridays).
We will use the online system WebWork (https://courses1.webwork.maa.org/webwork2/ucsd-wi14-math20c-bucur/), a service hosted by the Mathematical Association of America (MAA). Your username is the same as in TED (e.g. scooper if your UCSD email is scooper@ucsd.edu) and your password is your PID all in small caps (e.g. a12345678).
This service is provided free to the students, so there is nothing additional you have to pay for.
All homework must be completed by the due date. Answers will be made available after the due date, so no late submissions will be accepted.


Students are encouraged to discuss the homework among themselves, but remember that everyone gets a slightly different version of each problem.

Although you are required to submit only the HW problems listed below, you are expected to do additional problems from the book on your own until you understand the material.



Remember that on exams you will be required to show your work, not just give the final answer. This is an aspect that the online hw system lacks. Therefore, as requested, I will post a list of problems to help with understanding the material, going over in discussion section and office hours, and preparing for exams. I suggest you write down solutions for them, as you would on a test, but do not turn them in!
