Question 1

Consider a cable suspended between two points. Assuming its deflection is described by a second-order linear homogeneous equation, derive the auxiliary equation from \(y = e^{mx}\) to determine the nature of its solution.

💡 Hint: Think about finding the discriminant to classify roots into distinct, repeated, or complex.

Question 2

A second-order differential equation describes the temperature distribution in a rod: \(\frac{d^2T}{dx^2} - λT = 0\). Explore solutions for different values of \(λ\) and interpret their implications in real-world contexts.

💡 Hint: Consider how the signs of the coefficients affect the solution type.
