Question 1
What is the standard form of the one-dimensional wave equation?
- $$\\frac{\\partial^2 u}{\\partial t^2} = c^2 \\frac{\\partial^2 u}{\\partial x^2}$$
- $$\\frac{\\partial u}{\\partial t} = c \\frac{\\partial^2 u}{\\partial x^2}$$
- $$u = c^2 t^2 + x^2$$
💡 Hint: Look for the equation that involves second derivatives.
Question 2
True or False: The wave equation can only be applied to sound waves.
- True
- False
💡 Hint: Consider other examples of wave phenomena.

Question 1
Given a vibrating string fixed at both ends, write the general solution using Fourier series. Consider the fixed conditions at $u(0,t)=0$ and $u(L,t)=0$.
💡 Hint: Think about how to incorporate boundary conditions into the Fourier expansion.
Question 2
Solve the one-dimensional wave equation with initial conditions $u(x,0) = sin(x)$ and $u_t(x,0) = 0$ on the interval $[0,\pi]$ with Dirichlet conditions.
💡 Hint: Remember to apply the boundary conditions to derive the specific solution.
