Two three dimensional vectors can be multiplied to make a vector that is perpendicular to both. This is the Cross Product, and it only makes sense in three dimensions.

Enter the two vectors, the first in A: and the second in B:.

It is important to put the first one in A, since

Now click on . The answer appears in the lower middle of the window.

You can do calculations with the result by moving the answer to the left side

or to the right side .

Cross-product is quite different from Dot-Product and Scalar Product.
