Writing clearly helps promote clear
thinking, so we will focus some of our attention on learning to write
more clearly.
An overall guideline is to write proofs in a form that you could
understand if you looked back at the assignment a year after completing
the course (try this with previous work!) or in a form that is
understandable to another student who is not in the course with you.
Writing for each assignment should follow guidelines for that
assignment and all previous
assignments.
These guidelines are adapted from those developed by Dr.
Tracy Payne.
Abbreviations are as follows:
(M)
|
Mechanics
|
| (P) |
Presentation
|
(O)
|
Organization
|
(L)
|
Logic
|
(E)
|
Enhancement
|
Assignment 1.3
| (M) |
Use complete, clear, concise, grammatically correct
English sentences.
|
(P)
|
Include carefully drawn, precise
pictures to illustrate your proof. Clearly label on the picture
the information
you
are given or derive in the course of your proof. |
Assignment 1.5
(O)
|
Use organizational structure
and short phrases to make the direction and intent clear to the
reader. Use indentation, skipped lines, headings, and phrases
like "first we will show", "next", "the
last step is", "we are now able to", and others to tell the reader
where you are headed. |
| (L) |
Good writing requires and should reflect clear thinking. Be careful to justify each
conclusion you draw as following by hypothesis or from a previous
theorem or result. |
Assignment 2.2 & 2.3
(P)
|
Include sufficient detail so the reader can easily follow the train of thought.
|
| (L) |
Each object you use in the
course of your proof must either be
- chosen to be arbitrary,
- assumed to exist,
- or shown to exist.
You must explicitly and carefully state the origin of any object you
refer to.
|
Assignment 2.4 & 2.5
(L)
|
When you apply a theorem or
previous result, it should be clear which objects you are applying it
to.
|
| (L) |
When you apply a theorem or
previous result, you should fully justify in your proof that
the hypothesis of the theorem is satisfied. |
