Algebra 2

You may have learned about vectors in two-dimensional coordinate space, but did you know that vectors can be three-dimensional, too? With an introduction to 3-Vectors, you will learn about 3-Vector Components, such as the Magnitude of 3-Vectors, and the Direction of 3-Vectors. You will practice operations involving 3-Vectors include the Cross Product, and Multiplying 3-Vectors by a Scalar.
