NONLINEAR FIRST-ORDER ODEs • No general method of solution for 1st-order ODEs beyond linear case; rather, a variety of techniques that work on a case-by-case basis. Examples: i) Bring equation to separated-variables form, that is, y′ =α(x)/β(y); then equation can be integrated. Cases covered by this include y′ =ϕ(ax+by); y′ =ϕ(y/x).

How to transform a second-order ODE (ordinary differential equation) into a system of two first-order ODEs If you have a single second-order ODE (an ODE containing a second-derivative), you can actually just use a simpler substitution trick to transform it into a system of two first-order ODEs, which you can solve using by finding the eigenvalues and eigenvectors .
