My book on determining the interval doesn't do a good job on explaining how to do it, it just remarks on how it is analogous to the second order, which makes sense, but there is a problem:

In section 3.2, the book shows a few examples on determining where it exists, but these problems involve initial conditions. In 4.1, no initial conditions are given, it simply shows a rather ugly equation and says find the interval where it is guaranteed to exist, but how?
