The writeup of homework should be clear and concise. In particular:
Equations shall be used sparingly, as part of a story. The story shall present the argument of the problem concisely and accurately. Sketch diagrams with proper labels where necessary, but only in the context of the story. Equations without complete sentences don't mean anything.
Answers shall be boxed, so I don't have to hunt for them.
Homework shall be in pen or else typed using LaTeX/LyX or something similar. Very light pencil is unacceptable.
If I cannot easily read your handwriting, I will ask that you type your homework.
Homework not meeting these standards will be returned to be redone.
