In this section we want to look at an application of Mallet Hammer Handles Java Mini Mallet Hammer City derivatives for vector functions. Actually, there are a couple of applications, but they all come back to needing the first one.
With vector functions we get exactly the same result, with one exception. While, the components of the unit tangent vector can be somewhat messy on occasion there are times when we will need to use the unit tangent vector instead of the tangent vector.
First, we could have used the unit tangent vector had we wanted to for the parallel vector. However, that would have made for a more complicated equation for the tangent line. Do not get excited about that. Next, we need to talk about the unit normal and the binormal vectors. The unit normal is orthogonal or normal, or perpendicular to the unit tangent vector and hence to the curve as well.
They will show up with some regularity in several Calculus III topics. The definition of the unit normal vector always seems a little mysterious when you first see it. The above definition is the first of several essential definitions that we will see in this textbook. They are essential in that they form the essence of the subject of linear algebra: learning linear algebra means in part learning these definitions.
All of the definitions are important, but it is essential that you learn and understand the definitions marked as such. Specifying a set in this way is called set builder notation. All mathematical notation is only shorthand: any sequence of symbols must translate into a usual sentence. Equivalent means that, for any given list of vectors v 1 , v 2 , Objectives Understand the equivalence between a system of linear equations and a vector equation.
