Consider a second order nonhomogeneous, linear differential equation of the form:
a^2y'' + a^1y' + a^0y = g(x)
where y is the dependent function which is a function of the independent variable x; ao, a1, and a2 are constant coefficients; and g(x) is called the input function Using the Method of Undetermined Coefficients requires a guess for the particular solution, yp(x), based on the form of the input function.
Match each guess for the particular solution, yp(x), with its appropriate input function g(x).
A. yp(x) = (Ax + B) cos(3x) + (Cx + D) sin(3x)
B. yp(x) = A cos(3x) + B cos(2x) + Csin(3x) + Dsin(2x).
C. yp(x) = A cos(3x) + B sin(3x).
D. yp(x) = Ae^x cos(2x) + Be^xsin(2x).
E. Does not match any of the options.
1. g(x) = cos(2x) + sin(32).
2. g(x) = xcos(3x).
3. g(x) = cos(3x).
4. g(x) = e^x sin(2x).
5. g(x) = xsin(2x).

Suppose you just purchased a digital music player and have put 8 tracks on it. after listening to them you decide that you like 4 of the songs. with the random feature on your player, each of the 8 songs is played once in random order. find the probability that among the first two songs played (a) you like both of them. would this be unusual? (b) you like neither of them. (c) you like exactly one of them. (d) redo () if a song can be replayed before all 8 songs are played.
