Abstract
Dedicated to Solomon Marcus, the current paper continues a recent series about our meetings. Trying to recreate the spirit of those meetings, we first propose a discussion which started as a high-school problem. The main part of the current paper consists in a section about racks. It presents elements of trigonometry in racks, and Euler formulas associated in this framework
