Can you think of an example of a 2X2 matrix where AB=-BA?

I haven't taken linear algebra in two years, and I want to appear SMRT in front of my friend. Any ideas?

Keep your mouth shut and you'll look like a genius!

You can teach a monkey to make PNB & J sandwiches, but he's not going to eat them.

Yes, I can A & B would both be the identity matrix 😉

but the right side would be -I

A can be anything if you make B the zero matrix 🙂

 

[Random Variable]

(a 0)(0 0)
(0 0)(0 b)

Yeah AB can't = 0, forgot to state taht.

I gave you one above:

(a 0)(0 0)
(0 0)(0 b)
