Not really a homework problem, just a general question.

2. Relevant equations

Sorry, I don't yet know how to create arrays/matrices in latex (this is a gif)

3. The attempt at a solution

In the above image, why is [itex]c_{1}[/itex] positive, [itex]c_{2}[/itex] negative, and [itex]c_{3}[/itex] positive?

Aside from that, I think I understand the rest. I would assume c from the formula to be the unit vectors denoting direction, A would be the first vector in the product, and B would be the second. From there,

[itex]c_{1}[/itex] times [itex](a_{2}b_{3} - b_{2}a_{3})[/itex]

would be the [itex]c_{1}[/itex] component of the product and so on...

But why would the y/j component be negative in the formula?
