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.

Rolle's Theorem & Mean Value Theorem
An illustration of the Mean Value Theorem. Rolle's Theorem is included as a special case.
Rolle's Theorem: An Interactive Exploration
This applet shows interactively the points in which the Rolle's Theorem for a real function holds true.

You can type the function expression in the f(x)field, and the interval start and end points in the a and b fields.  Move point c on the x-axis in order to view the different positions assumed by the tangent line to the function graph.

Verify whether the following functions satisfy the hypothesis of Rolle's Theorem in the given intervals, and hence find the point(s) c as prescribed by the theorem:

f(x) = 1 + |x| on [-1,1]
f(x) = -x^2 - x + 2 on [-1,0]
Optimization of Rectangles - Area & Perimeter
This applet allows students to investigate the optimal area and optimal perimeter of a rectangle.  Drag the vertices Width and Length to change the dimensions of the rectangle.

What is the optimal area of a rectangle?
Find as many pairs of dimensions as you can that give a perimeter of 20cm. 
Which of these pairs gives the optimal area?

What is the optimal perimeter of a rectangle?
Find as many pairs of dimensions as you can that give an area of 36 sq. cm. 
Which of these pairs gives the optimal perimeter?
Optimization - Maximizing Area
Maximizing the Area of a 3-Sided Rectangle
What is the length and width of the 3-sided rectangle that maximizes the area?
Newton's Method
This is a dynamic illustration of Newton's Method for approximating roots of functions. Drag point x1 to change the initial guess and see how the subsequent approximations change.

Use the slider to change to another example.
Newton's Method - User Defined Function
This dynamic illustration demonstrates the procedure involved in the use of Newton's method for approximating the roots of an equation.

In this version, the user can enter their own equation.
