21. A smooth curve that is not closed is often referred to as a smooth arc. 22. The following animation illustrates how a smooth curve can be meaningfully assigned a precise length: 23. The Ulanga with its broad smooth curves was easy to navigate by a light-draught steamer. 24. He put smooth curves through his experimental data points. 25. So what looks like a single smooth curve is really series of smaller S curves. 26. The diffeomorphism ? " s " therefore carries the smooth curve onto this small circle. 27. This can be done by considering equivalence classes of smooth curves with the same direction. 28. Note that not all orderings of the points are the natural ordering of a smooth curve . 29. This allowed the construction of smooth curved surfaces. 30. To avoid creating stress risers, the drop was formed as smooth curves , not as sharp corners.
