2008, 2016 Zachary S Tseng B 1 1 Second Order Linear Differential Equations Second Order Linear Equations with constant coefficients; Fundamental solutions; Wronskian; Existence and Uniqueness of solutions; the characteristic equation; solutions of homogeneous Linear Equations ; reduction of Order ; Euler Equations In this chapter we will study ordinary Differential Equations of the standard form below, known as the Second Order Linear Equations : y + p(t) y + q(t) y = g(t). homogeneous Equations : If g(t) = 0, then the equation above becomes y + p(t) y + q(t) y = 0. It is called a homogeneous equation. Otherwise, the equation is nonhomogeneous (or inhomogeneous). Trivial Solution: For the homogeneous equation above, note that the function y(t) = 0 always satisfies the given equation, regardless what p(t) and q(t) are.
