Sorry I meant x not * :)

I need to find the length and direction of u x v, and I have:

u = i x j

v = j x k

So first I will find:

Then the length is 1 and direction is i - j + k.

Am I doing this correctly?

For " " use "\times" not "x".

Sorry and thanks for the tip.

I meant cross product, I didn't notice that * could mean dot product :)

Why does skeeter's solution is so different from mine? Are they the same thing?
