First order differential equations are the equations that involve highest order derivatives of order one. They are often called “ the 1st order differential equations Examples of first order differential equations: Function σ(x)= the stress in a uni-axial stretched metal rod with tapered cross section (Fig. a),

The general solution to the first order partial differential equation is a solution which contains an arbitrary function. But, the solution to the first order partial differential equations with as many arbitrary constants as the number of independent variables is called the complete integral. The following n-parameter family of solutions is a complete integral if .

Partial Differential Equations (PDE's) Learning Objectives 1) Be able to distinguish between the 3 classes of 2nd order, linear PDE's. Know the physical problems each class represents and the physical/mathematical characteristics of each. 2) Be able to describe the differences between finite-difference and finite-element methods for solving PDEs.

First Order Differential Equations Introduction. Differential Equations are equations involving a function and one or more of its derivatives.. For example, the differential equation below involves the function \(y\) and its first derivative \(\dfrac{dy}{dx}\).
