QUESTION 5 (a) The equation 1=0 is to be solved in the domain 0

QUESTION S (a) The is to be solved in the domain O x 3, 0 S y 3. subject to the boundary conditions Using Ax Ay l, find an solution to the equation by using A.D.L method. Use the initial values I) = "(1.2) = I) = u(2.2) = I, and do one row traverse followed by one column ITURN OVERI APM3711 OCT/NOV 2020 (b) Assume that the ion 2u x2 y2 With given boundary conditions is to solved in a rectangular grid With values, (i) Explain What is an iterative for this problem. and how such a method proceed (ie how new values would be calculated) Explain this problem would by the SOR (successive overrelaxation) method. and how such a method would proceed (i.e. how new values would be calculated).
