Did we have \(det(e^{tA}) = e^{tr(A)}\) in the lecture? Carl (talk) 23:51, 19 June 2015 (CEST)


Well actually it's \(det(e^{tA}) = e^{tr(tA)} = e^{t\cdot tr(A)}\).

The first equality is a property of the matrix exponential, see Wikipedia: [[1]] and Trubo used that property too in the lectures.

The second equality follows from the linearity of the trace. So I don't see any problems on using that.
