Second Order Linear Differential Equations
Proposition 12.1 Let r be a root of the equation (12.9) r2 ar b 0 Then erx is a solution to the homogeneous equation: (12.10) y ay by 0 Equation (12.9) is called the auxiliary equation of the differential equation (12.10). To verify the propo-sition, let y erx so that y rerx y r2erx. Substituting into equation (12.10): (12.11) r2erx are rx berx ...
