How do you find the characteristic equation of a differential equation?
Example: Solve the equation y − 6y +9=0, Solution: the characteristic equation is r2 − 6r +9=0, r1 = r2 = 3; The two independent solutions are y1 = e3x, y2 = xe3x; the general solution is: y = C1e3x + C2xe3x. One can check that by plugging in the differential equation.

How do you find the characteristic equation of a matrix?
The equation det (M – xI) = 0 is a polynomial equation in the variable x for given M. It is called the characteristic equation of the matrix M. You can solve it to find the eigenvalues x, of M. The trace of a square matrix M, written as Tr(M), is the sum of its diagonal elements.

What is a second order homogeneous differential equation?
Homogeneous differential equations are equal to 0 The differential equation is a second-order equation because it includes the second derivative of y. It’s homogeneous because the right side is 0. If the right side of the equation is non-zero, the differential equation is called nonhomogeneous.

How do you solve a linear second order differential equation?
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
What is the general equation of the second order nonhomogeneous linear equation?
Theroem: The general solution of the second order nonhomogeneous linear equation y″ + p(t) y′ + q(t) y = g(t) can be expressed in the form = yc + Y
How do you transform an equation into a first order equation?
we can transform this into a first-order ODE with some simple variable substitution. Define x 2 ( t) = y ′ ( t) and x 1 ( t) = y ( t) for some equation y ″ = A y ′ + B y. Then we have x 1 ′ = y ′ = x 2 and x 2 ′ = y ″ = A x 1 − B x 2. Thus we can simplify our original equation into a system of equations
What is second order and third order derivative?
The Order is the highest derivative (is it a first derivative? a second derivative? etc): This has a second derivative d2y dx2 , so is “Second Order” or “Order 2” This has a third derivative d3y dx3 which outranks the dy dx , so is “Third Order” or “Order 3”
