I informally introduce limits in geometry using inscribed and circumscribed
polygons to bound the area and perimeter of a circle and also in area and
perimeter of fractals strictly from a numeric viewpoint.

In pre-calc, we investigate bounding behavior of functions to a particular
tolerance along with behaviour at points of discontinuity and approaching

We also talk about Zeno's paradox and infinite geometric sequences.

All of these instances are treated from an intuitive point of view and
verified numerically.(limited to the capability of the calculator)
