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...
