How can I solve the following exercise?
Let V be the vector space defined on the field R of n dimensional. Let T : V V be a linear transformation such that T n 1 0, T n = 0 and B = { x , T ( x ) , T 2 ( x ) , , T n 1 ( x ) } it is a basis for V. Find a matrix associated with the linear transformation T.
I think the only way to explicitly determine the matrix associated with the linear transformation T, is to define T as
T ( α 1 x + α 2 T ( x ) + + α n 1 T n 1 ( x ) ) = α 1 x + α 2 T ( x ) + + α n 1 T n 1 ( x ) .

We have
T [ α 1 x + α 2 T ( x ) + + α n T n 1 ( x ) ] = α 1 T ( x ) + α 2 T 2 ( x ) + + α n 1 T n 1 ( x )
To put it another way: if we rewrite B as B = { v 1 , v 2 , , v n }, then we have
T [ α 1 v 1 + α 2 v 2 + + α n v n ] = α 1 v 2 + α 2 v 3 + + α n 1 v n 1
Thus, the matrix of T with respect to the basis V is
( 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 0 )
