You may use this form to leave suggestions, comments, and contributions. Information provided will be kept
confidential. Please be aware of the *MathWorld* Frequently Asked Questions page
before writing.

Please consider becoming a *MathWorld* contributor by filling out the following form. Your contributions will be gratefully
acknowledged together with those of other *MathWorld* contributors. For additional
information about contributing material, visit the FAQ on contributing.

There are currently a number of entries in *MathWorld* that are either incomplete or in the process of being modified. A
complete listing of entries "under construction" is also kept up-to-date, as is a list of
entries missing specific pieces of information, and
entries containing out-of-date hyperlinks. Help in fleshing out these
entries would be especially appreciated.

- If you'd like to
**report a typo**, please include two parts in your message:- Quote the sentence or line that contains the error.
- Give the correct version of the line or error.

- If you'd like to
**add to an existing entry**, please provide:- The sentence preceding a good entry point for your addition.
- Exact wording for your entry, in plain text, Mathematica, or TeX.
- A vector-based image, if necessary. Mathematica or a vector program may help.
- For references, please follow the

**report mathematical news**, please:- Provide a link to your source.
- Give a short summary for why your submission is newsworthy.
- We cannot report news on unpublished proofs of Fermat's Last Theorem or the Goldbach Conjecture. Also, note that we cannot review proofs.

- To report a
**typesetting glitch**, please:- First, try a page refresh. If that fails, please mention which browser you are using.
- Attach a screenshot, annotated and trimmed to the pertinent area.
- Equation number references currently display as (◇) instead of the correct number. This is a known bug that we hope to fix soon.

- We always appreciate
**kind words**. You might also visit Eric Weisstein's personal site. - For
**help with a mathematical problem**, consider:- For questions about formulas, notation, and special functions, please first try the formula search and list of notations at The Wolfram Functions Site.
- Wolfram Research's powerful mathematics software Mathematica can be used to solve many mathematical problems.
- The Math Forum's Ask Dr. Math provides homework help.
- For calculus help, calc101.com provides step-by-step answers.
- For other homework help, please see our FAQ.

- We are regrettably not able to respond to questions of the form "
**Is formula**" Almost always, the answer is "yes." If you have checked a formula yourself and have cogent reason to believe that it contains a typo, please send us a typo report stating, if possible, why the current formula is wrong and what changes are needed to correct it.*x*correct?
