There's some dispute over this challenge's title. The author originally created it as "Многочлены Чебышёва". A user edited it to "Chebyshev Polynomials" (an imperfect translation, but the translation commonly used in mathematics, and that is also used in the challenge body). A minor edit war erupted over the title. This meta post aims to solve this dispute, and any future disputes.
- Stack Exchange sites are in English (with a few exceptions - namely the foreign language Stack Overflow sites), so English-only challenge titles are consistent with the rest of the site.
- Having an English title makes it much easier to search for the majority of the userbase.
- English translations may be imperfect or ambiguous.
Note: this is not trying to address the usage of non-English words or characters when they are in common use in English (like loanwords or mathematical symbols).
