Mathematics 317: Evaluation of Homework

Written proofs will be evaluated for mathematical completeness and correctness, and for the quality of the writing.

I will use a 12-point scale, with 8 points for the mathematics and 4 points for the writing.

[A: 10-12 points] The proof is complete and correct.
[B: 7-9 points] The proof is nearly complete and correct. It has only a minor error or omission.
[C: 4-6 points] The proof has a substantial error or omission.
[D: 1-3 points] The proof has major errors or omissions but makes some progress.
[F: 0 points] The attempted proof makes no progress.

Submit proofs after editing your notes into final form.

Documents containing material crossed out or erased are not acceptable.

Address the proof to a reader who has taken a year course in calculus.
Begin with a statement of what is to be proved.
State your assumptions; tell what you will prove and indicate the method of proof.
Use the pronoun "we."
If you type your proof, set variables in italic type.
Write in complete sentences.
Use paragraph breaks to set off major steps in the proof,
such as the necessity and sufficiency parts of a biconditional.
About displayed equations:
- Break text to display important or long equations.
- Write the text surrounding a displayed equation so that together with the display it makes a complete sentence.
- Number a displayed equation if you refer to it elsewhere in the text.
Tell the reader when the proof is complete.

Solutions of computational problems will be graded on an 8-point scale, with 4 points for correctness and 4 points for clarity.

[A: 7-8 points] The solution is complete and correct.
[B: 5-6 points] The solution is nearly complete and correct. It has only a minor error or omission.
[C: 3-4 points] The solution has a substantial error or omission.
[D: 1-2 points] The solution has major errors or omissions but makes some progress.
[F: 0 points] The attempted solution makes no progress.
