Title: Solving the Laplace Equation over a Square Mesh with Boundary Conditions Solve the Laplace equation ∇²u = 0 over the square mesh of side four units, satisfying the following boundary conditions. Round to three decimal digits for the first three iterations. u(x,0) = 0 for 0 ≤ x ≤ 4 u(x,4) = 4(12 + x) for 0 ≤ x ≤ 4 u(0,y) = 12y for 0 ≤ y ≤ 4 u(4,y) = 4y^2 for 0 ≤ y ≤ 4

Solve the Laplace equation ∇²u = 0 over the square mesh of side four units, satisfying the following boundary conditions. Round to three decimal digits for the first three iterations: [16] u(x,0) = 0 for 0 ≤ x ≤ 4 u(x,4) = p(12 + x) for 0 ≤ x ≤ 4 u(0,y) = 3py for 0 ≤ y ≤ 4 u(4,y) = py^2 for 0 ≤ y ≤ 4
2.3.11. Solve Laplace's equation inside a rectangle: ∇²u = ∂²u/∂x² + ∂²u/∂y² = 0 subject to the boundary conditions u(0, y) = g(y) u(x, 0) = 0 u(L, y) = 0 u(x, H) = 0. (Hint: If necessary, see Sec. 2.5.1.)
