- The method of power series is actually the oldest method of numerical
- solution of differential equations, but is now usually considered "not
- in style." There ARE many cases in which it is far better than the
- usual ones, and of course many where it is not. HOW is not much of
- a problem; as to WHEN, this is a matter of art, not science.
-
- Power series are also used for theoretical reasons. Old DE books
- spend some time on the topic.
