Hello, I'm Girth Summit. An edit that you recently made to Spherical coordinate system seemed to be a test and has been removed. If you want more practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! Girth Summit  (blether) 09:04, 20 February 2019 (UTC)
