In Problems 1-3, find the general solution, and describe the long-term behavior of y(t): exponen-
tial growth, exponential decay, simple oscillations, damped oscillations, or growing oscillations.
Hint: if there are multiple terms in the solution, the qualitative behavior is determined by the
largest term, i.e. the term that wins out for large t.
1. y"+y' 6y = 0.
2. y" 4y' + 4y = 0.
3. yy' + y = 0.
4. Consider a mass-spring system with mass m = 1, spring constant k = 2, and damping
constant b = 2. Set up the equation of motion, and find the general solution y(t). Describe
the long-time behavior as in problems 1-3. Is this overdamping, critical damping, or
underdamping?
