E251 -- De integratione aequationis differentialis (m dx)/√(1-x4) = (n dy)/√(1-y4)
(On the integration of the differential equation (m dx)/√(1-x4) = (n dy)/√(1-y4))
Summary:
Euler takes it for granted that
m/n
is a rational number. In addition to the equation given in the title, Euler also
handles the cases where there is an arbitrary whole fourth-degree function or a special 6th-degree function under the
radical sign.
According to the records, it was presented to the St. Petersburg Academy on April 30, 1753.
