PLEASE ANSWER NUMBER 6 MATH 221 : PLEASE GIVE DETAILED SOLUTIONS AND CORRECT ANSWERS. I WILL REPORT TO BARTLEBY THOSE TUTORS WHO WILL GIVE INCORRECT ANSWERS.
In Exercises 1- 4, apply the Jacobi method to the given system of
linear equations, using the initial approximation (x,, x2, . ..,Xx„) =
(0, 0, . . . , 0). Continue performing iterations until two successive
approximations are identical when rounded to three significant digits.
