Consider the following system of equations: 121x1x2=0x1+121xixi+1=bi,(2i8)x8+121x9=7 You must solve the system using Gauss-Seidel iteration, with a relaxation weighting factor of =0.6. The right hand sides of the system of equations, b, and the vector of initial guesses, x0, are b=095198507,andx0=111302211,respectively. What is the third (3rd) iteration of x8 ? Your answer must be correct to 0.0001 , so use long format to make sure you have enough digits in your answer! -0.0683 (with margin: 0.0001) Consider the following system of equations: 74x17x2=27xi1+74xi7xi+1=bi,(2i8)7x8+74x9=2 You must solve the system using Gauss-Seidel iteration, with a relaxation weighti factor of =0.6. The right hand sides of the system of equations, b, and the ve of initial guesses, x0, are b=245968452,andx0=212201133,respectively. What is the 4th iteration of x3 ? Your answer must be correct to 0.0001 , so use long format to make sure you hav enough digits in your answer! 0.132 (with margin: 0.0001)
