Consider the discretized square plate in Figure 1
Figure 1: Discretized Square Plate
1. Write a system of linear equations for this system and clearly identify the matrix A in the matrix equation Ax=b.
2. Compute the determinant of A.
3. Compute the classical adjoint matrix (i.e., the adjugate matrix) of A.
4. Using your answers from problems 2 and 3, solve for A-1 and x.
5. Use Cramerâs rule to check your answer by solving for just x1 and x4.
