The Cross Product

Although the cross product is often paired with the dot product, the two are quite different. The result of a dot product calculation is a scalar, while the result of a cross product calculation is a vector. Dot products are used to measure angles and lengths, while cross products are used to measure areas and volumes. In this worksheet, we introduce the cross product and explore its unique character. First, we load some packages.
