ADVANCED MATH (You may use excel or write the solutions properly. Rate will be given.)

x1 + 3x- x3 + 8x4 = 15

10x- x+ 2x3 + x4 = 6

-x+ 11x- x3 + 3x4 = 25

2x1 - x2 + 10x3 - x4 = -11

Assume that x10 = 0, x20 = 0, x30 = 0, x40 = 0. 

Round off to 4 decimals in each iteration.

Using Successive Over Relaxation with w = 1.2,

 

a. what are the approximate values of x1, x2, x3, x4  at the fifth iteration?

x= ?

x2 = ?

x= ?

x= ?

b. What is the absolute error at the 5th iteration?
