Theorem 2.23.
Let T be a linear operator on a finite-dimensional vector space V, and let B and B' be
ordered bases for V. Suppose that Q is the change of coordinate matrix that changes B'-
coordinates into B-coordinates. Then
[T] B = Q-¹[T] BQ.
Proof.
Let I be the identity transformation on V. Then T = IT = TI; hence, by Theorem 2.11
(p. 89),
Q[T], = [1] [T] = [IT]} = [TI] = [T]/I]} = [T],Q.
Therefore [T] =Q-¹[T] µQ.
