Note:
To change the value of a, you must highlight with the mouse the number
at the right of a = . To do this, you
move the cursor to the number, press down the left mouse
button and move across the number. After releasing the left mouse button
you can then type the new value for a. It is important that you ONLY
highlight the number before you begin typing. There is a difference between
the image above and the LiveMath notebook: the term a =
appears in the animation above the graph while in the notebook it is below the
graph.
Also, note that the animation also demonstrates the changing of the function. iThis is not a part of the original function.
