Chapter 4. Working with Linear Second Order Differential Equations
In This Chapter
Solving second order differential equations that are both linear and homogeneous
Reveling in the three roots: real, distinct roots; complex roots; and real, identical roots
Are linear second order differential equations keeping you up at night? You know the ones. They look like this:
y″ + p(x)y′ + q(x)y = g(x)
where
and
Then this is the chapter for you because it's all about practicing solving linear second order differential equations that are also homogeneous.
Note: In this chapter, you only solve differential equations for regions where p(x), q(x), and g(x) are continuous functions (that is, where they don't take quick jumps in value). Usually there will be an initial condition, such as
y(xo) = yo
and
y′(xo) = yo′
