Transcribed Image Text:In Exercises 1–6, use the variation of parameters to find a particular solution.
1. \( y'' + 9y = \tan 3x \)
2. \( y'' + 4y = \sin 2x \sec^2 2x \)
3. \( y'' - 3y' + 2y = \frac{4}{1 + e^{-x}} \)
4. \( y'' - 2y' + 2y = 3e^x \sec x \)
5. \( y'' - 2y' + y = 14x^{3/2} e^x \)
6. \( y'' - y = \frac{4e^{-x}}{1 - e^{-2x}} \)
