Solution Summary
This solution shows how to determine the general solution with a step-by-step explanation.
Solution Preview
The homogeneous part of the equation is:
y" + y = 0
and the associated characteristic equation is r^2 + 1 = 0
So the roots are r1 = -i, and r2 = i
Therefore, the solution to the homogeneous part is
yh = ...
