Round off to 3 decimal place The 3x3 system below has solutions x₁=1, Xa=-2 and x3 = 4x+2x2-2x3 = 0 2x1-6x2 - 2x3 = 14 3X₁-X₂ +4X3 = 5 i Explain why this system is not quickly strictly diagonally dominant (hereafter 5DD) -(0) (iu) Using the initial approximation X₁0 =0.75, X = -1.75 and x3 = -0.35, apply three iterations of the Jacobi Method to the above system (0) () (iii) Taking the initial approximation X₁₂ =0.75, X₂ = -1.75 and x300) = -0.35, apply three iterattiers of the Jacobi Method to the above system (iv) Will the Jacobi and Grauss-Siedel iterates For all 3x3 linear systems that are not SDD always eliverge? If not, give an example of a system that is not SDD. but for which the Jacobi and Grauss- Siedel iterates converge to the solution of the system.
