### Policies

Homework will usually be assigned on Thursday and will be due by the end of class the following Thursday. No late homework will be accepted. The two lowest homework scores will be dropped. Homework must be stapled and clearly labelled with your name. Students are encouraged to collaborate on homework assignements. Collaboration means working together to frame problems, devise approaches, and compare results. The final work, however, must be the work of the individual student, indicating that you alone prepared the work and understand the material. This means you must write up solutions independently.### Corrections

If you believe there is a mistake on any grading, you have*two weeks*from when the item is handed back to bring it to my attention.
