## Gauss-Jacobi (answer in 2 minutes)

1) Form the equations for X, Y and Z

2) Let X = A, Y = B, Z = C

3) Enter D = (equation for A)

4) Enter  :   ##ALPHA (colon)

5) Enter E = (equation for B)

6) Enter  :   ##ALPHA (colon)

7) Enter F = (equation for C)

8) Enter  :   ##ALPHA (colon)

9) Enter A = D   ##ALPHA =

10) Enter  :   ##ALPHA (colon)

11) Enter B = E   ##ALPHA =

12) Enter  :   ##ALPHA (colon)

13) Enter C = F   ##ALPHA =

FINAL EXPRESSION
D = (EQUATION FOR A) : E = (EQUATION FOR B) : F = (EQUATION FOR C) : A = D : B = E : C = F

14) Press CALC

15) Enter initial value for B

16) Enter initial value for C

17) You ll get the value of D ie A ie X  (note it down)

18) Press =

19) Enter initial value for A

20) Press =

21) You ll get the value of E ie B ie Y  (note it down)

22) Press =

23) You ll get the value of F ie C ie Z  (note it down)

24) Press =

25) Press =

26) Press =

27) Press =

28) Press =

29) Press =

30) You ll get the value of ie ie X (note it down)

31) Repeat Repeat Steps 11 to 20 till you get matching values for A, B and C
