Interactive Animations
Calculus is the study of change.  The ability to change a parameter and immediately see the result can demonstrate that change and how things are related during that change.  Many of these concepts are much easier to explain if that change, the motion, can be visually demonstrated in class.  Therefore, this is a perfect place for the use of computer animations.  

All animations were created using the GeoGebra dynamic mathematics software application located on GeoGebra's website.
Please be patient! It takes awhile for these to load.

Tangent Line Sliding Along the Function
Zooming in on a Tangent Line
This animation is a version of the common demonstration that a smooth curve becomes indistinguishable from its tangent line when viewed under a sufficiently high power microscope.
Vertical Tangent Line - A Point of Non-Differentiability
This is a pretty straightforward interactive animation depicting the geometric convergence of a tangent line to a vertical tangent line, where at that point, the derivative does not exist. The slope of the tangent (which converges to the derivative) is also displayed. ​
Falling Ladder - Related Rates Demo
As you can see, the speed of the bottom of the ladder at point A is constant, but the speed of the top of the ladder at point B changes.  This is a demo from Stewart's Calculus, Concepts and Contexts, 4th Edition. 
Cone - Related Rates Demo
As you can see, the cone fills faster at the beginning and then slows down the closer it gets to the top.
Light Pole - Related Rates Demo
In the distance versus time plot notice that DistHomerPlot (which is the distance Homer is from the lamp post at time t) is a straight line.
  • Why is it a line? 
  • What is the slope of this line?
​The plot ShadowTipPlot (which is the distance the tip of the shadow is from the lamp post at time t) is also a straight line.
  • Why is it a line? 
  • What is the slope of this line?

Homer Simpson, who is 6 ft tall, is walking away from a 18 ft tall lamp post at a speed of 8 ft/s. How fast is the tip of his shadow moving along the ground when he is 100 ft from the lamp post?
