A second order differential equation is an equation involving the unknown function y, its derivatives y' and y'', and the variable x. We will only consider explicit differential equations of the form,

In the previous chapter we looked at first order differential equations.  In this chapter we will move on to second order differential equations.  Just as we did in the last chapter we will look at some special cases of second order differential equations that we can solve.  Unlike the previous chapter however,

Applications of Second-Order Differential Equations; Second-order linear differential equations have a variety of applications in science and engineering. In this section we explore two of them: the vibration of springs and electric circuits.

In Additional Topics: Applications of Second-Order Differential Equations we will further pursue this application as well as the application to electric circuits. In this section we study the case where G x 0, for all x, in Equation 1. Such equations are called homogeneous linear equations.
