[edit] Abel's identity
こんにちわ and also a warm welcome from me. Thank you for your contribution on Abel's identity. I slightly changed the notation; for instance, you used both W(x) and W(y1, y2) for the Wronskian. I hope you don't mind. I think the proof of the identity goes a bit too much into detail; after all, Wikipedia is an encyclopedia and not a textbook. You might want to read Wikipedia:Manual of Style (mathematics) for some general advice on how to write mathematics on Wikipedia. Unfortunately, the technology is not perfect, so this is not always straightforward. I hope to see more contributions from you! Cheers, Jitse Niesen (talk) 23:42, 1 December 2005 (UTC)
[edit] Unspecified source for Image:Great_Big_Sea.jpg
Thanks for uploading Image:Great_Big_Sea.jpg. I noticed that the file's description page currently doesn't specify who created the content, so the copyright status is unclear. If you did not create this file yourself, then you will need to specify the owner of the copyright. If you obtained it from a website, then a link to the website from which it was taken, together with a restatement of that website's terms of use of its content, is usually sufficient information. However, if the copyright holder is different from the website's publisher, then their copyright should also be acknowledged.
As well as adding the source, please add a proper copyright licensing tag if the file doesn't have one already. If you created/took the picture, audio, or video then the {{GFDL-self-no-disclaimers}} tag can be used to release it under the GFDL. If you believe the media meets the criteria at Wikipedia:Fair use, use a tag such as {{fairusein|article name}} or one of the other tags listed at Wikipedia:Image copyright tags#Fair use. See Wikipedia:Image copyright tags for the full list of copyright tags that you can use.
If you have uploaded other files, consider checking that you have specified their source and tagged them, too. You can find a list of files you have uploaded by following this link. Unsourced and untagged images may be deleted one week after they have been tagged, as described on criteria for speedy deletion. If the image is copyrighted under a non-free license (per Wikipedia:Fair use) then the image will be deleted 48 hours after 14:28, 25 March 2007 (UTC). If you have any questions please ask them at the Media copyright questions page. Thank you. MECU≈talk 14:28, 25 March 2007 (UTC)
[edit] Image:Great_Big_Sea.jpg
Thanks for uploading Image:Great_Big_Sea.jpg. I notice the 'image' page specifies that the image is being used under fair use, but its use in Wikipedia articles fails our first fair use criterion in that it illustrates a subject for which a freely licensed image could reasonably be found or created that provides substantially the same information. If you believe this image is not replaceable, please:
- Go to the image description page and edit it to add
{{Replaceable fair use disputed}}, without deleting the original Replaceable fair use template. - On the image discussion page, write the reason why this image is not replaceable at all.
Alternatively, you can also choose to replace the fair use image by finding a freely licensed image of its subject, requesting that the copyright holder release this (or a similar) image under a free license, or by taking a picture of it yourself.
If you have uploaded other fair use media, consider checking that you have specified how these images fully satisfy our fair use criteria. You can find a list of 'image' pages you have edited by clicking on this link. Note that any fair use images which are replaceable by free-licensed alternatives will be deleted one week after they have been uploaded, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you. MECU≈talk 14:28, 25 March 2007 (UTC)
