The Genuinely Nonlinear First-Order Equationates representing the first partial derivatives of the unknown field, however, it is possible to recover most of the features of the quasi-linear case so that, ultimately, even the solution of the general non-linear equation can be reduced to the integration of a system of ordinary differential equations.

The One-Dimensional Wave Equationial and boundary-value problems. The main result presented in this chapter is the so-called d’Alembert solution, expressed within any convex domain as the superposition of two waves traveling in opposite directions with the same speed. Some further applications are explored.

The Diffusion Equationentails an arrow of time, a concept related to the Second Law of Thermodynamics. On the other hand, many of the solution techniques already developed for hyperbolic equations are also applicable for the parabolic case, and vice-versa, as will become clear in this chapter.
