I Need Help With A Matrix Problem...

Sat Oct 21, 2006 1:00 am

Hey everyone...I'm sure someone here knows a little more about matrix algebra than I do, so I was hoping someone would be able to help me out with a problem I've been working on for a while...
_____________________________________________

Given the matrix A,

cos(x).............-sin(x)

sin(x)..............cos(x)

Determine the inverse of A
_____________________________________________

How are you supposed to get the given matrix down to the identity matrix,

1......................0

0......................1

Any help would me much appreciated!

Rgds,

Mike
