Just saw a edit summary of yours:


 * I explained why it doesn't matter which 90 degree rotation one chooses. In the preview, I can't properly see the minus sign in the equation Rv=-R'v, I hope that gets fixed one I publish the changes

This is a know bug with google chrome and we are wainting for the next release to see it fixed. The help desk has a couple of threads on the issue. --Salix alba (talk): 13:02, 19 January 2021 (UTC)
