5: Cross (Vector) Product of Vectors

- 5.1: The Cross Product
- In this section, we develop an operation called the cross product, which allows us to find a vector orthogonal to two given vectors. Use the cross product to find the area of a parallelogram.
- 5.2: Vector Cross Product
- Another kind of vector multiplication is the vector product, also known as the cross product, which results in a vector perpendicular to both of the factors. The vector product has the distributive property and the anticommutative property, and is obtained by multiplying the magnitudes of the two vectors by the sine of the angle between them. The direction of the vector product can be determined by the corkscrew right-hand rule.
