8. Consider any damped harmonic oscillator equation d² y dt2 m d²y dt² dy dt +b. + ky = 0. (a) Show that the sum of any two solutions is another solution. (b) Using the result of part (a), solve the initial-value problem dy +3 + 2y = 0, y (0) = 2, v(0) = -3. dt (c) Using the result of part (a) in Exercise 7 along with the result of part (a) of this exercise, solve the initial-value problem dy TH nairU (x). d² y +3. + 2y = 0, y(0) = 3, v(0) = -5. dt² dt (d) How many solutions to the equation d² y dy dt² dt +3. + 2y = 0 do you get if you use the results of Exercise 7 and this exercise along with the guess-and-test method described in this section?
