Question
For the differential equation
y" + 8y + 16y = sin(7x)
Part 1: Solve the homogeneous
equation
The differential operator for the
homogeneous equation is
List the complementary functions
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)
Therefore the particular solution
must be made up of the functions
Substituting these into the
differential equation, we find the
particular solution is
