Hello, I'm Falcon Kirtaran. I noticed that you made a change to an article, Integration by substitution, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. FalconK (talk) 21:34, 30 January 2022 (UTC)

Hello, I'm Lastsoundofdefense. I noticed that you added or changed content in an article, François Recanati, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you. Lastsoundofdefense (talk) 22:08, 7 December 2022 (UTC)
