Solve the following differential equations:
(1) "-- by =0
(2) "+ 2y =0
(3) " + 2y +y =0
(4) " + 9y = 0
(5) " - G/ + 13y = 0
(6) " - 4 + 5y = 0
(7) "- 4y + 4y = 0
(8) " + 6y + 10y = 0
(9) " + -0
(10) "+ 6y + 13y = 0
(11) 10y" - 3y -y=0
(12) 4" + 4y + 10y =0
Solve the initial value problems:
(13) y" - 4y +3y = 0; y(0) - -1, / (0) = 3
(14) y" + 4y= 0; y() 1, () = -4
(15) 6y" - - y = 0; y(0) = 10, g'(0) = 0

12(0) -
(17) y"+ 7y' + 12y = 0; y(0) = -1,(0) = 0
(18) 36y" – 12y + y = 0; y(0) = 3, (0) =

(a) Suppsoe that y is a solution of the differential equation
ay" + by + cy = 0.
Let :(r) - s(r - ro) where ro is an arbitrary real number. Show that
a:" + be' + es =0
(b) Let z1(a) = yn(r- ro) and z2(x) = 2(r - ro), where yG = CI1 + caa is the general solution to ay" +
by +cy = 0. Show that se = e +gz is also a general solution of ay" + by/ + cy =0.
