Math 20F - Linear Algebra - Instructor: Sam Buss - Spring 2003

Written Homework Assignments

Handing in homeworks: Homework assignments are due in class on Friday.  Late homework assignments are accepted only in exceptional circumstances.
Important: Label your homework with (a) your name, (b) your student ID, and (c) your section time.  Your name should be identifiably similar to your name in the official UCSD course roster on student link.  Your section time is used only to help return the homework to you.

We do not yet know whether we will have resources to grade homework assignments, but we will at least track whether they are done.  They are a required part of the course!

If you work jointly with other students, you must still do your own work.  This means you must write up your solution yourself, not directly copying from another source.  If someone shows you an answer, you should wait at least 10 minutes, and then try to write up the answer on your own.  This is to ensure you are really learning the material.
