Abstract
This chapter begins our study of second order linear differential equations, which are equations of the form
where a(t), b(t), c(t), called the coefficient functions, and f(t), known as the forcing function, are all defined on a common interval I. Equation (1) is frequently made into an initial value problem by imposing initial conditions: y(t 0) = y 0 and y′(t 0) = y 1, where t 0 ∈ I.

Notes
- 1.
A grammatical note: We say f 1, …, f n are linearly independent (dependent) if the set {f 1, …, f n } is linearly independent (dependent).
- 2.
We assume in this proof some familiarity with matrices and determinants. See Chap. 8 for details.
- 3.
