#### Characteristic equation

• In mathematics, the characteristic equation (or auxiliary equation) is an algebraic equation of degree n \, on which depends the solutions of a given n \, th-order differential equation. The characteristic equation can only be formed when the differential equation is linear, homogeneous, and has constant coefficients.
