  This is a translation into English from the original Latin of Leonhard
Euler's Exercitatio analytica, Nova Acta Academiae Scientarum Imperialis
Petropolitinae 8 (1794), 69-72; E664 in the Enestrom index. In it Euler uses
the infinite product identity for sin to prove some properties of the series
for the Riemann zeta function for even n.
