The Maple procedure works as follows. Students enter a function, a point in the domain of the function, an expected limit, and the maximum value of epsilon to be considered. The procedure then generates an animation where each frame corresponds to a value of epsilon. Each frame displays the graph of the function, highlighting the region of the range corresponding to epsilon and the region of the domain corresponding to delta. Additionally, a graph of the delta values associated with each value of epsilon is provided. Students can apply modeling skills to find a formula for delta in terms of epsilon.
Besides providing the Maple code for the procedure and some sample frames from the output, this
paper includes some tips on using the display command in Maple and on distributing Maple code in
