A partial differential equation (PDE) is an equation involving functions and their partial derivatives; for example, the wave equation (1) Some partial differential equations can be solved exactly in the Wolfram Language using DSolve[eqn, y, x1, x2], and numerically using NDSolve[eqns, y,...
3.1.4.2 Partial Differential Equations If a function has more than one independent variable, the total change in the function will depend on more than one variable. In such a case, we are faced with a “partial differential equation” (PDE). Eq. 3.3 was an example of a function that depe...
We will draw attention to the physical and technical interpretations of the presented problems and mention their solution by the Galerkin method. At the end of this chapter, we shall show, on a simple example, how to find an error estimate for the approximate solution....

Partial-Differential-Equations (1)Partial Differential Equations Partial differential equations (PDEs) are a fundamental concept in mathematics and physics, playing a crucial role in describing the behavior of various physical phenomena such as heat conduction, fluid dynamics, and quantum mechanics. These...
For example: a)(dydx)2−xy5dydx+siny=0,b)xd2ydx2−dydx=0, are differential equations. The order of the differential equation is given by the derivative of the highest order, a) is a first-order differential equation and b) is a second-order ...
