The determinant of an 𝑛×𝑛 matrix is equal to the 𝑝𝑟𝑜𝑑𝑢𝑐𝑡 of its eigenvalues The trace is equal to the 𝑠𝑢𝑚 of its eigenvaluespic.twitter.com/sWdUWUeP0y

Right but what does that mean? Like for example the det of a matrix is how much the matrix stretches volume or area
it's just another invariant under a change of basis .. these are the only two invariant tensors for GL(n, R)

Do you know about the epsilon tensor and the kronecker delta
