So this expression up here is also equal to 0. Or another way to view it is that if g is a solution to this second order linear homogeneous differential equation, then some constant times g is also a solution. So this is also a solution to the differential equation. expandingarray

"To solve a linear second order differential equation of the form d2ydx2 + pdydx+ qy = 0 where p and qare constants, we must find the roots of the characteristic equation r2+ pr + q = 0 There are three cases, depending on the discriminant p2 - 4q.

Phase portrait of … WebbI assume you are talking about the second case. The slope dy/dx tells us that for a given number of steps on the x axis, we must take a certain number of steps on the y axis. So you should read dy/dx = 1.5 as dy/dx = 1.5/1, which means that for one step on the x axis, we go one step and a half on the y axis.

WebbSuppose we have a second-order ODE such as: y ″ + 2 y ′ + 2 y = cos ( 2 x), y ( 0) = 0, y ′ ( 0) = 0 We can turn this into two first-order equations by defining a new dependent variable. For example, z ≡ y ′ ⇒ z ′ + 2 z + 2 y = cos ( 2 x), z ( 0) = y ( 0) = 0. Now introduce the vector
