This chapter extends the qualitative approach to differential equations to second-order linear differential equations. These can be classified into several different types. Each type can be illustrated by a phase plane diagram, which is a two-dimensional analog of the phase line studied in the previous chapter, and provides a geometrical picture of the behaviour of the system.

摘要

This chapter extends the qualitative approach to differential equations to second-order linear differential equations. These can be classified into several different types. Each type can be illustrated by a phase plane diagram, which is a two-dimensional analog of the phase line studied in the previous chapter, and provides a geometrical picture of the behaviour of the system.
