For any characteristic polynomial determined from A - eI (where A is a nxn matrix, e is an eigenvalue and I is the identity matrix),
is it a rule that the coefficient associated with the char. polynomail term of highest degree must be positive ?
My tutor made a theory that if the characteristic polynomial's coefficient of highest power is negative, then divide it through by -1 to make it positive.
Im not sure why it has to be positive, so I'd really like some clarification
thanks
