Question

NOTE: WRITE MATLAB CODE then the results for each QUESTIONS: Q1: For the system of the equations [2x; + 3xy + x3 = 9 x2 + 2x2 + 3x3 = 0 3x; +x2+2x3 = 8) compute the unknowns Xı, X2, and X3 using the inverse matris method. Q2: Simplify the complex number z and express it both in rectangular and polar form. (3+ j4)(5 + j2)(2 260°) (3+j6)(1+12)

Answer 1

`Hey,

Note: If you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

1)

clc

clear all

close all

format short

A=[2,3,1;1,2,3;3,1,2];

b=[9;6;8];

x=inv(A)*b;

x1=x(1)

x2=x(2)

x3=x(3)
