Algebra 2

We are used to describing the world around us in terms of three dimensions: width, height, and depth. We might also discuss the fourth dimension: time. However, in mathematics and physics, there are many more dimensions in the universe. Our N-Dimensional Vectors course introduces the concept of N-Space and how we define the components of N-Vectors. We explore Dot Product Properties and how to calculate Distance in N-Space. We will also introduce an important inequality, The Cauchy-Schwarz Inequality, which has applications in N-Dimensional Vectors and more.
