Solve the following equation using...

Solve the following equation using the method of variation of parameters

1. y'' - y' - 2y = e^2x

2. y'' + 2y' + y = (e^-x) /x

3. y'' + 4y = tan 2x

4. y'' + 4y = tan^2 2x

5. y'' + 4y = sin^2 2x

6. y'' - 3y' + 2y = cos (e^-x)

7. y'' - 4y' + 4y = (e^2x) / x

8. y'' + 6y' + 9y = (e^-3x) / x^2 +1

1. y'' - y' - 2y = e^2x

2. y'' + 2y' + y = (e^-x) /x

3. y'' + 4y = tan 2x

4. y'' + 4y = tan^2 2x

5. y'' + 4y = sin^2 2x

6. y'' - 3y' + 2y = cos (e^-x)
