Cross product in physics
WebApr 21, 2007 · Answers and Replies. where a and b are arbitrary vectors, sigma is the pauli spin operator. I was just wondering what the dot product and cross product were. Because a and b can be 2x1, 2x2, 2x3, etc... I'm not sure how to take a dot product of matricies much less a cross product. Since it specifies dot and cross, i assume that it is not just a ...
