The unit tangent vector at t is defined to be = Note: Recall that a curve is “smooth” on an interval if is and. on the interval. Thus, “smoothness” is sufficient to guarantee that a curve has a unit tangent vector. Exercise 1a (Section 12.4 #2): Determine and sketch the unit tangent vector to the curve …

Let C be a smooth curve. The direction of the tangent vector can vary from point to point according to the nature of the curve. Example 37 . i) If the curve is a straight line, then T (t) is a constant . vector valued function, and hence = 0. ii) If the curve undulates gently, then the tangent vector . T (t) changes direction slowly along the ...

((t) is tangent to the curve for all t, and that to create a unit vector, we just divide a vector by its magnitude. Thus, the unit tangent vector . T (t) for any value of t is defined by: T (t) will always points in the direction of the orientation of the curve. Practice: Find the unit tangent vector . T (t) for a circle of radius a traced out ...

The unit tangent vector indicates the direction of the curve. We would like to be able to measure how fast the curve changes, which corresponds to how fast the direction of the unit tangent vector changes. The curvature measures how quickly the curve changes direction at a specific point. It can be shown to be found by the following formula.
