] | $$x\frac{dy}{dx} - y = (x^2 + y^2)^{1/2} $$ is an ODE of the homogeneous kind. The usual method to solve it is to let $y(x)=x\:f(x)$
This leads to an ODE of the separable kind easy to solve.
The final result is $y=c\:x^2-\frac{1}{4\:c}$ | The substitution $y = u x$ makes this into a separable differential equation. |
