Find the solution of the initial-value problem
y" - 7y" +9y' - 63y = sec 3t, y(0) = 2, y'(0) = 3, y″(0) = 69.
A fundamental set of solutions of the homogeneous equation is given
by the functions:
y₁(t) = eat, where a =
y₂(t)=
=
Y3(t) =
A particular solution is given by:
=
Y(t) = [
to
+
+
Therefore the solution of the initial-value problem is:
y(t) =
ds - y₁(t)
.
-
