Challenge Problems

Push your limits with challenges.

Question 1

Given the wave equation $$\frac{\partial^2 u}{\partial t^2} = c^2 \frac{\partial^2 u}{\partial x^2}$$ with initial conditions $u(x,0) = cos(x)$ and $\frac{\partial u}{\partial t}(x,0) = -sin(x)$, use Laplace Transforms to find the solution.

💡 Hint: Ensure you apply both initial conditions carefully during the transformation.

Question 2

Identify the limitations of Laplace Transforms in solving non-linear PDEs. Provide an example where the Laplace Transform would fail.

💡 Hint: Consider both the types of terms in the equation and boundary conditions required.
