Great Videos

"Tutorials for the Calculus Phobe" - Videos that explain calculus concepts. These are excellent (I haven't viewed them all, but I'm impressed with what I've seen.) Part of calculus-help.com.

Derivatives

Calculus Grapher - (no formulas) can drag points of function and show the Derivative and/or Integral AMAZING ! (from PhET).

Function, Derivative and Integral - (no formulas) can drag points of function and show the Derivative and/or Integral (from cut-the-knot)

Applets and Tools

• Calculus Demonstration/Investigation Tools - (most are under the "Algebra" section--you can also Find-In-Page for key words, such as limit) Experiment with the applets
  • Piecewise Functions, Limits, and Continuity - does left-hand, right-hand, and 2-sided limit.
  • Function Flyer - one of the best applets on the web. Allows user to input function, manipulate x, and manipulate coefficients.
• Learning about Rate of Change - Cost per minute and total cost.
• Spotting Numbers Applet - a great applet for learning about patterns. Can be used on many levels from elementary through algebra.
• Circumference is the limit of the perimeter of polygons (as the number of sides approaches infinity). (From Cut-the-Knot.).

Misc. Notes

A recursive formula tells you how to get a number in the sequence from the one right before it.  (So if you want to know the 46th term, you'd have to know the first 45 first.)

A direct formula tells you how to get any number in the sequence.  (So you can get the 46th term directly.)

To figure out if something is a function, see if each x-value has exactly one y-value.  If the equation can be solved for y (and there is just one formula for y) it probably is a function.  Be aware of things like y² (y-squared).  y² + x = 10 is not a function.  If x is 1, there are two values for y that work.  (Can you find them? --what happens when you solve for y?)
