Is There More Than Meets the Eye in Finding the General Solution for a Matrix?

Click For Summary
SUMMARY

The discussion focuses on finding the general solution for the matrix equation A[x; y; z] = [0; 0; 0], where A is a 3x3 matrix. The user expresses confusion regarding the interpretation of the term "general solution" and seeks clarification on how to express the variables x, y, and z in terms of the matrix elements a, b, c, d, e, f, g, h, and i. The key takeaway is that the general solution involves expressing the variables in terms of free variables derived from the system of equations represented by the matrix.

PREREQUISITES

Homework Statement



Given the matrix A=[...], find the general solution of; A[x;y;z]=[0;0;0]

Homework Equations





The Attempt at a Solution



This question has me lost. When I look at that it tells me x, y and z are all equal to 0. Is there something I'm missing, perhaps in the words 'general solution'?
 
Physics news on Phys.org
A[x;y;z]=[0;0;0] is stating in matrix form the general solution to a set of 3 equations of variables x,y,z all = 0. For example If A=[a b c;d e f;g h i], how does one write what x, y and z are in terms of a,b,c,d,e,f,g,h and i IF ax+by+cz=0, dx+ey+fz=0 and gx+hy+iz=0? That's what I got out of the question.
