Question
Please give the correct functions annihilated by the differential operator
For the differential equation y"+ 16y + 64y = sin(6z)
Part 1: Solve the homogeneous equation
The differential operator for the homogeneous equation is (D+8)-
List the complementary functions
-8x
-8x
„re
Part 2: Find the particular solution
To solve the non-homogeneous differential equation, we look for functions annihilated by the differential operator (a multiple of the differential
operator from above) re&r
Therefore the particular solution must be made up of the functions sin(6x). cos ( 6x)
Substituting these into the differential equation, we find the particular solution is
17
sin(6x)
2500
625 COS (6r)
