Nonhomogeneous Second-Order Differential Equations
www.math.pitt.eduNonhomogeneous Second-Order Differential Equations To solve ay′′ +by′ +cy = f(x) we first consider the solution of the form y = y c +yp where yc solves the differential equaiton ay′′ +by′ +cy = 0 and yp solves the differential equation ay′′ +by′ +cy = f(x). Since the derivative of the sum equals the sum of the derivatives, we will have a final

System of First Order Differential Equations
www.unf.eduWhen b(t) · 0; the linear first order system of equations becomes x0(t) = A(t)x(t); which is called a homogeneous equation. As in the case of one equation, we want to find out the general solutions for the linear first order system of equations. To this end, we first have the following results for the homogeneous equation,
