4 Partial Differential Equations
fab.cba.mit.edu/classes/864.17/text/pde.pdf4 Partial Differential Equations Partial differential equations (PDEs) are equations that involve rates of change with respect to continuous variables. The configuration of a rigid body is specified by six numbers, but the configuration of a fluid is given by the continuous distribution of the temperature, pressure, and so forth.
Wave equation - Wikipedia
https://en.wikipedia.org/wiki/Wave_equationThe wave equation is a second-order linear partial differential equation for the description of waves—as they occur in classical physics—such as mechanical waves (e.g. water waves, sound waves and seismic waves) or light waves. It arises in fields like acoustics, electromagnetics, and fluid dynamics.. Historically, the problem of a vibrating string such as that of a musical …
