You can use GeoGebra to compute vector products, also called cross products. 
     GeoGebra Instruction 1
Algebra     View     and         Graphics     View     under         View     in         Menu.         Algebra View, enter         Cross(<vector>, <vector>)
where you type in the vectors you want to compute the product of in the <vector>     fields. Use parentheses for your vector coordinates. Remember that the order of the         vectors matters! 
Example 1
Given the vectors and , Find the vector product
You find the vector product by following the instructions above. The solution will be shown in Algebra View. The picture below shows what the solution of the vector product will look like when you follow the instructions above.
