Math 262 -- Fall 09 -- Homework

Homework assignments

 

When doing homework makes you feel like the guy in the lion's mouth you need to join a study party and/or come to office hours. I guarantee you'll fell like a lion crushing mathematics!

Please remember that up to 3 people can and should hand in 1 homework paper. Also please keep in mind that I have to read what you write. Have pride in your work and let that pride in your work come through. Homeworks that are typed and available as pdfs can be sent to me via email.
