12.7. Getting Serious Answers with Series Solutions
Is a tough differential equation like this one bogging you down?
y″ + xy′ + 2y = 0
Then try solving it with a series solution, which allows you to assume that y can be expanded in a power series like this:
For practice solving differential equations using series solutions, flip to Chapter 8. You can also check out this great online resource: tutorial.math.lamar.edu/Classes/DE/SeriesSolutions.aspx.
