Find the solution to the two-dimensional wave equation


1. Find the solution to the two-dimensional wave equation

ð2u/ðt2= ð2u/ðx22u/ðy2, 0

boundary conditions u(0,y,t)= u(1,y,t)= u(x,0,t)=u(x,1,t)=0

2. Solve the two-dimensional wave equation for a quarter-circular membrane

0

The boundary condition is such that u=0 on the entire boundary.

3. Consider Laplace's equation

ð2u/ðt2 = c2(ð2u/ðx22u/ðy2)-kðu/ðt with k>0.

a. Give a brief physical interpretation of this equation.

b. Suppose that u(x,y,t)=f(x)g(y)h(t)

What ordinary differential equations are satisfied by f, g, and h?
