anyone help me on this.
the eigenvectors are 2,-1,3.
This is B,
1 1 1
2 1 2
3 2 4
This is B-1,
0 2 -1
2 -1 0
-1 -1 1
I cant seem to workout how you manage to get from B to B-1.
Naisy, what are you doing in this material? You simply MUST be able to find the inverse of a simple 3x3 matrix.
Cpt. Black used some terms with which you simply must be familiar. If you are not, you must look them up and get familiar. It will not serve you at all to remain absent this information.
