Solve the linear system 211-1₂ +13 2r₁ +2r₂+2r3 -11-22 +223 = = 4, iteratively. (a) Use the Jacobi method with r(0)=0 to find the 10th Jacobi iterations. (b) Compute the exact solution (any way you like) and use it to find the oc-norm of the error in 5th Jacobi iterate. (c) Use the Gauss-Seidel method with a(0)-0 to find the 10th Gauss-Seidel iteration.
