Talk:Lagrange's trigonometric identities

Merge discussion
This article should be merged with List of trigonometric identities, in particular the section Other sums of trigonometric functions, as these identities are just the same formulae as given there with φ set to zero and some rearrangement.-- JohnBlackburne wordsdeeds 17:16, 13 November 2011 (UTC)


 * This is why I seldom bother contributing to Wikipedia anymore. Someone puts in the work to contribute something they think other people will find useful -- and then someone like you comes along and just deletes everything they wrote, without a second thought.  A lot of people have stopped contributing because of this, and it's ruining Wikipedia.


 * So, at this point, I really don't care. Since before I even wrote the first version of this article, you've been deleting links to it, deleting links from it, and now you want to delete the whole thing.  Why don't you just go ahead and delete this whole article now -- that's obviously your goal. Delete all of Wikipedia if you want to. I'd rather spend my time on other projects that aren't being overrun by you Deletionists. SimpsonDG (talk) 01:39, 15 November 2011 (UTC)


 * It's not deletion, it's merging. Take a look at List of trigonometric identities, at the point I indicated. You will see formulae there which are generalisations of these ones, so are arguably more useful. But it would be good to add these to that article, as alternatives which have a name attached and are referenced. That will make that article more useful and mean anyone looking for Lagrange's trigonometric identities will find other closely related formulae, improving the encyclopaedia, with your contributions still present in that article.-- JohnBlackburne wordsdeeds 02:23, 15 November 2011 (UTC)


 * I had planned to expand this article, including the history of the identities, original uses, some current uses etc., but there's obviously no point now -- all of that information will be deleted as a result of this impending "merge" (really a less aggressive form of a deletion).


 * It's really too bad. When Wikipedia first started, it was a very nice project.  You could contribute to existing articles or start new ones, and it was fun to watch other users improve on what you had written -- expanding it, making it clearer, adding more information, etc.  It really worked well for a number of years.  But those days are over.  I've found lately that if you try to contribute anything at all, somebody immediately deletes your contribution, citing some obscure violation of the minutiae of thousands of Wikipedia rules and policies. I've sometimes spent hours and hours arguing with someone over making even the tiniest change to an article; then after having soundly won the argument, had my contribution deleted anyway.  Start a new article on some topic, and it gets almost immediately deleted.  Try correcting or adding to an existing article, and your edits are immediately reverted.  Try to look up an article you wrote a few years ago, and it's gone. There's just no point in spending time on the Wikipedia project anymore, when anything you do is immediately deleted. After many years of contributing to Wikipedia, this is the last straw.  I won't be contributing to it anymore, and will be joining the increasing number of people who are abandoning the Wikipedia project. SimpsonDG (talk) 03:16, 16 November 2011 (UTC)
