(Higher order riation of parameter) Consider the n-th order linear equation
g(n)
+
-Σªs(2)y(¹) = g(n) + ªn-1(2)g(0-¹) + - - - + ao(z)y = r(s).
...
Assume that y₁,, are n-independent solutions of the associated homogeneous equa-
tion. Prove that a particular integral of the given ODE is
Up = [v., where =
u
R₁
Here W is the wronskian of y₁,...,n and R is the determinant obtained by replacing
i-th column of W by [0,0,...,0, (x)].
