Goal: Develop a technique to solve the (somewhat more general) first order PDE ∂u ∂x +p(x,y) ∂u ∂y = 0. (1) Idea: Look for characteristic curves in the xy-plane along which the solution u satisfies an ODE. Consider u along a curve y = y(x). On this curve we have d dx u(x,y(x)) = ∂u ∂x + ∂u ∂y dy dx.

You may need to use an “integrating factor” to solve a first-order ordinary differential equation. You will definitely need to use an integrating factor to solve inseparable first-order differential equations. You can use the integrating factor for separable first-order ODEs too if you want to, though it takes more work in that case. Question: Solve The First-order Differential Equation Y'- Y = 4 This problem has been solved!
