Question
Using the Method of Undetermined Coefficients, determine the form of a particular solution to the differential equation (Do not evaluate coefficients) y”+25y=3t^3sin5t
Write the form of a particular solution. Choose the correct answer below.

A. \( y_p(t) = t \left( A_3 t^3 + A_2 t^2 + A_1 t + A_0 \right) \cos 5t + t \left( B_3 t^3 + B_2 t^2 + B_1 t + B_0 \right) \sin 5t \)

B. \( y_p(t) = \left( A_3 t^4 + A_2 t^3 + A_1 t^2 + A_0 \right) e^t \cos 5t + \left( B_3 t^4 + B_2 t^3 + B_1 t^2 + B_0 \right) e^t \sin 5t \)

C. \( y_p(t) = \left( A_3 t^3 + A_2 t^2 + A_1 t + A_0 \right) \cos 5t + \left( B_3 t^3 + B_2 t^2 + B_1 t + B_0 \right) \sin 5t \)

D. \( y_p(t) = t \left( A_3 t^3 + A_2 t^2 + A_1 t + A_0 \right) e^t \cos 5t + \left( B_3 t^3 + B_2 t^2 + B_1 t + B_0 \right) e^t \sin 5t \)
