Step-by-step explanation:
1 ) Given that
For a non homogeneous part , we assume the particular solution is
2 ) Given that
For a non homogeneous part , we assume the particular solution is
3 ) Given that
y′′ + 4y′ + 20y = −3sin(2x)
For a non homogeneous part −3sin(2x) , we assume the particular solution is
4 ) Given that
y′′ − 2y′ − 15y = 3xcos(2x)
For a non homogeneous part 3xcos(2x) , we assume the particular solution is
