Hello, I'm RA0808. I noticed that in this edit to Automatic differentiation, you removed content without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry, the removed content has been restored. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. RA 0808 talkcontribs 20:06, 3 October 2017 (UTC)
