Problem:
Illustrate graphically the epsilon-delta definition of limits to obtain evidence that

Visualization:

Given that epsilon = 0.1, the following graph shows that using delta = 0.1 is clearly insufficient.

However, the following graph shows that using delta = 0.005 works.

These graphs were generated by Microcalc.

For this visualization, we have detailed instructions for the following software packages:

In addition, instructions are also provided for the
