Examples of unit tangent vector. Note None of these examples are mine. I have chosen these from some books. I have also given the due reference at the end of the post.Autor Dr. Aspriha PetersUnit Normal Vector. Just as knowing the direction tangent to a path is important knowing a direction orthogonal to a path is important. When dealing with real-valued functions we defined the normal line at a point to the be the line through the point that was perpendicular to the tangent line at that point.A vector processing unit is a processor element with built-in instructions that perform multiple calculations on floating-point vectors (one-dimensional arrays of 32-bit or larger numbers) simultaneously having at least one vector arithmetic logic unit.
Where is a parameterization variable is the arc length and an overdot denotes a derivative with respect to . For a function given parametrically by the tangent vector relative to the point is therefore given by
