I wasn't sure about this question on my exam. Let eigenvalues be 0, 1, -1(adsbygoogle = window.adsbygoogle || []).push({});

Is it true that

a. Not Invertible

b. Diagonalizable

c. Orthogonal

a. True, since the determinant is 0

b. I'm not sure, but I chose False b/c I had an eigenvalue of 0

c. True, ah not sure either

LOL!
