Hello. Thank you for your contributions to Wikipedia.

I noticed your recent edit to Rotation (mathematics) does not have an edit summary.&#32;Please be sure to provide a summary of every edit you make, even if you write only the briefest of summaries. The summaries are very helpful to people browsing an article's history.

Edit summary content is visible in:


 * User contributions
 * Recent changes
 * Watchlists
 * Revision diffs
 * IRC channels
 * Related changes
 * New pages list
 * Article editing history

Please use the edit summary to explain your reasoning for the edit, or a summary of what the edit changes. With a Wikipedia account you can give yourself a reminder to add an edit summary by setting. The text you changed was correct before. If you think it needs to be changed, please explain in your edit summary what you are changing and why. — Anita5192 (talk) 18:00, 23 January 2021 (UTC)


 * x'=x*cosθ+y*sinθ and y'=y*cosθ-x*sinθ in the picture but equations are written x'=x*cosθ-y*sinθ and y'=y*cosθ+x*cosθ — Preceding unsigned comment added by Erhan Süt (talk • contribs) 22:50, 1 March 2021 (UTC)


 * The picture was added July 28, 2018, long after the section was written and does not agree with the text in the section, so I removed it. Thank you for pointing this out.—Anita5192 (talk) 06:15, 2 March 2021 (UTC)
