Zooming In on a Smooth Curve

Notice how the curve appears to "flatten" as we zoom in; the zoomed-in curve (also shown below) appears almost straight.

Note We have zooomed in to a particular point on the curve; that is, we have always kept that point in the center of the viewing window as we zoomed. Zooming in on different points leads to views of different portions of the curve.
