Hello,
in the following code I would like to replace x with T in Delta_X so as to
illustrate
the Cayley Hamilton theorem by doing everything by hands.
Is it possible ?
Best regards.
Christophe BAL
=========================
var('a b c d e f')
T = matrix([
[a, b, c],
[0, d, e],
[0, 0, f]
])
T_X = T - x*identity_matrix(3)
Delta_X = det(T_X)
