Question

Let T be a linear operator from R3 to R3, where T is a 3x3 matrix. How do I determine if T is decomposable or indecomposable?

Answer 1

find det?

Answer 2

I can't-he hasn't taught us how to do it yet so we can't use that method :(

Answer 3

I don't understand decomposable
if i not wrong
if matrix T =(a b c,d e f,g h k)
T=(ax+dy+gz,bx+ey+hz,cx+fy+kz)

Answer 4

it is you need??

Answer 5

Where T is a linear operator for some vector v. I have to determine some how if T is decomposable or indecomposable with respect to the vector v. I don't know how to show that though
