For the underdetermined coefficents can you explain your guess??Thank you!!

The image contains four differential equations. Here is the transcription of the equations: (a) \( y'' - 4y' + 4y = 0 \) (b) \( y'' + y' - 2y = e^{-x} \) (c) \( y'' + 2y' + 5y = 7 \sin(x) \) (d) \( y'' + y = \tan(x) \), \(-\frac{\pi}{2} < x < \frac{\pi}{2} \) Explanation of Equations: 1. **Equation (a)**: This is a homogeneous second-order linear differential equation with constant coefficients. 2. **Equation (b)**: This is a non-homogeneous second-order linear differential equation with constant coefficients, where the non-homogeneous term is \( e^{-x} \). 3. **Equation (c)**: This is another non-homogeneous second-order linear differential equation with constant coefficients, where the non-homogeneous term is \( 7 \sin(x) \). 4. **Equation (d)**: This non-homogeneous second-order linear differential equation has a non-homogeneous term \( \tan(x) \), and it includes a domain restriction for \( x \) such that \(-\frac{\pi}{2} < x < \frac{\pi}{2} \). No graphs or diagrams are present in the image. The text is purely mathematical and presents the equations for educational purposes in the context of differential equations.
