1. Constant coefficient second order linear ODEs We now proceed to study those second order linear equations which have constant coefficients. The general form of such an equation is: a d2y dx2 +b dy dx +cy = f(x) (3) where a,b,c are constants. The homogeneous form of (3) is the case when f(x) ≡ 0: a d2y dx2 +b dy dx +cy = 0 (4)
