What Is a Vector?

A vector, in the simplest terms, is a set of numbers that describe a position or direction somewhere in a given coordinate system. Note that vectors are different from scalars, which are numbers that represent only a single value or magnitude. For instance, 60mph is a scalar value, but 60mph heading north can be thought of as a vector. Most of the vectors you will deal with in this book are properties of the curves and surfaces themselves . For instance, you will frequently deal with the slope of a curve or the normal vector to a specific point on a surface.
