Challenge Problems
Push your limits with challenges.
Question 1
Given the wave equation with initial conditions \( u(x, 0) = e^{-x} \) and \( \frac{\partial u}{\partial t}(x, 0) = 2e^{-x} \), find the expressions for \( f(x) \) and \( g(x) \).
💡 Hint: Think about how to apply the conditions to formulate the two functions.
Question 2
Apply D'Alembert's Solution for \( u(x, 0) = cos(x) \) and \( \psi(x) = \sin(x) \) and find the resultant wave function.
💡 Hint: Use the properties of the cosine function when finding specific solutions.
