Okay, I turned in a piece of homework the other day and my teacher said that I got one wrong. I was asked to solve for j x k or <0, 1, 0> x <0, 0, 1>. I said that the answer was i (<1, 0, 0>). But, try as I might that is the only answer that I am getting. Am I wrong? Is she wrong? Thanks.
Hello, dazygrl02!
You are right . . . she is wrong.
I said that the answer was: .
~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
There is a diagram for multiplying these unit vectors.

If the multiplication is clockwise, the product is positive.

If the multiplication is counterclockwise, the product is negative.
