**Animation: Secant approaching the Tangent (applet)**
*Paul Garrett, garrett@math.umn.edu *

This is the motion-picture version of the ** secant
** lines approach the ** tangent ** to a curve, so
that the slope of the tangent line is the **limit** of the
slopes of the secant lines.

This is one of the little things I don't seem to be able to simulate at
the blackboard...
