Euler's notation
I checked Euler's Mechanica, sive, Motus scientia analytice exposita v1 1736; and his Institutiones calculi differentialis, 1755, that could be found on https://archive.org/details/mechanicasivemot01eule and I can only see that Euler used Leibnizio's notation. I cannot see D operator in his books. SMZinovyev (talk) 03:14, 10 July 2023 (UTC)
