1. y" + 14y' + 58y = 0
a) Classify the system as overdamped, underdamped, or critically damped.
b) Suppose an external service F(t) = 71cos(t) + 43sin(t) is applied to the system above. Find the general solution to the resulting non-homogeneous differential equation.
c) Identify the transeitn solution and the steady state solution. Describe any long term behavior of the system.

a) Classify the system as overdamped, underdamped, or critically damped.
The characteristic equation is $\displaystyle r^2+ 14r+ 58= 0$. What are the roots of that? What are the definitions of "overdamped", "underdamped" or "critically damped"?

b) Suppose an external service F(t) = 71cos(t) + 43sin(t) is applied to the system above. Find the general solution to the resulting non-homogeneous differential equation.
Since "i" is NOT a root of the characteristic equation above, just look for a particular solution of the form Acos(t)+ B sin(t).

c) Identify the transeitn solution and the steady state solution. Describe any long term behavior of the system.
What are the definitions of "transient solution" and "steady state solution"?
