Euler's differential equation

In mathematics, Euler's differential equation is a first order nonlinear ordinary differential equation, named after Leonhard Euler given by^[1]

${\displaystyle {\frac {dy}{dx}}+{\frac {\sqrt {a_{0}+a_{1}y+a_{2}y^{2}+a_{3}y^{3}+a_{4}y^{4}}}{\sqrt {a_{0}+a_{1}x+a_{2}x^{2}+a_{3}x^{3}+a_{4}x^{4}}}}=0}$

This is a separable equation and the solution is given by the following integral equation

${\displaystyle \int {\frac {dy}{\sqrt {a_{0}+a_{1}y+a_{2}y^{2}+a_{3}y^{3}+a_{4}y^{4}}}}+\int {\frac {dx}{\sqrt {a_{0}+a_{1}x+a_{2}x^{2}+a_{3}x^{3}+a_{4}x^{4}}}}=c}$
