Talk:Wolfram Alpha

Yahoo Answers, late April 2012 http://answers.yahoo.com/question/index;_ylt=AmqM10Np_AK3eQ6heQBqFgEjzKIX;_ylv=3?qid=20120423184428AAb8yqw Brandon complained about some Mathematica commands not working in Wolfram Alpha. Bob suggested starting a web page "that easily accepts contributions of lists all the Mathematica notation that works and the substitutions and workarounds needed when the standard notation doesn't. ... test and date all the submissions so everyone could know when something worked and if WA fixed a problem or broke something."

This page won't quite fulfill Bob's suggestion that the web page easily accept contributions, and I don't know if Brandon has taken him up on that. If not, this page might be the next best thing. Alonso del Arte 20:15, 2 May 2012 (UTC)

Table[n^2, {n, 20}]	According to Brandon, this did not work correctly at one point.	According to Bob, April 2012, this does work correctly.
ChineseRemainder[{1, 2, 3}, {2, 3, 5}]		In April 2012, Brandon said this "works beautifully."
FixedPointList[Sqrt[#] + 1 &, 1.62]		Works correctly but some other expressions involving pure functions are misunderstood. Alonso del Arte 20:15, 2 May 2012 (UTC)
Plus@@IntegerDigits[9894976450123]	The "@@" syntax confuses the parser, Wolfram Alpha then thinks one is asking general information about the number. Alonso del Arte 20:15, 2 May 2012 (UTC)

Direct OEIS reporting

Near as I know, WA will report the (every?) OEIS sequence specifically when one types in something like "A129912". Certainly worth mentioning.--Bill McEachen (talk) 22:27, 19 February 2018 (EST)

It does seem to be true of entries that have been in the OEIS for more than five years or so. Alonso del Arte (talk) 00:13, 20 February 2018 (EST)
