Second Order Linear Nonhomogeneous Differential Equations; Method of Undetermined Coefficients We will now turn our attention to nonhomogeneous second order linear equations, equations with the standard form y″ + p(t) y′ + q(t) y = g(t), g(t) ≠ 0. A first order Differential Equation is Homogeneous when it can be in this form: dy dx = F( y x) We can solve it using Separation of Variables but first we create a new variable v = y x . The nonhomogeneous differential equation of this type has the form y′′+py′+qy=f(x), where p,q are constant numbers (that can be both as real as complex numbers). Do you feel less motivated now that exams are cancelled? Denition 1 A linear system of equations Ax = b is called homogeneous if b = 0, and non-homogeneous if b 6= 0. Therefore, for nonhomogeneous equations of the form \(ay″+by′+cy=r(x)\), we already know how to solve the complementary equation, and the problem boils down to finding a particular solution for the nonhomogeneous equation.
