(e) Again, if you have the components of two vectors, you can use the formula to find the cross product:
A x B = (AyBz - AzBy)i + (AzBx - AxBz)j + (AxBy - AyBx)k. Using the vectors A and B given in question 1b, find the cross product A x B. If you've studied linear algebra, you may recognize this as the determinant of the matrix:
i j k
Ax Ay Az
Bx By Bz
