4. Suppose the following functions are a general solution of: y(4) + azy" + azy" + a13 + a0y = 0 where a3, a2, a1, ay are constants. Use each general solution to determine the constants a3, a2, ɑ1, ao. (a) y(t) = c1 + ©zt + c3 cos(3t) + c4 sin(3t) (b) y(t) = c1 cos(t) + ©2 sin(t) + c3 cos(2t) + c4 sin(2t) %3D
