Second Order Differential Equation Solver Types Examples Methods Definition: characteristic equation. the characteristic equation of the second order differential equation ay'' by' cy=0 is. a\lambda^2 b\lambda c=0. \nonumber. the characteristic equation is very important in finding solutions to differential equations of this form. To solve a linear second order differential equation of the form. d 2 ydx 2 p dydx qy = 0. where p and q are constants, we must find the roots of the characteristic equation. r 2 pr q = 0. there are three cases, depending on the discriminant p 2 4q. when it is. positive we get two real roots, and the solution is. y = ae r 1 x be r 2 x.

Second order constant coefficient differential equations can be used to model spring mass systems. an examination of the forces on a spring mass system results in a differential equation of the form \[mx″ bx′ kx=f(t), \nonumber \] where mm represents the mass, bb is the coefficient of the damping force, \(k\) is the spring constant, and \(f. Repeated roots – in this section we discuss the solution to homogeneous, linear, second order differential equations, ay′′ by′ cy = 0 a y ″ b y ′ c y = 0, in which the roots of the characteristic polynomial, ar2 br c = 0 a r 2 b r c = 0, are repeated, i.e. double, roots. we will use reduction of order to derive the second.
