Question
**Problem 2: Solving Differential Equations with Undetermined Coefficients** Solve the following equations using the method of undetermined coefficients. (a) \(4y'' + 9y = 15\) (b) \(y'' - 16y = 2e^{4x}\) **Explanation:** - **Equation (a):** This is a linear homogeneous differential equation with constant coefficients. The equation can be solved by finding a particular solution and a complementary solution. - **Equation (b):** This is a linear non-homogeneous differential equation. The method of undetermined coefficients involves finding the complementary solution (general solution of the associated homogeneous equation) and a particular solution that satisfies the non-homogeneous part.
