Here we see a dialogue where students discuss combining limits with arithmetic.

Continuity is defined by limits.

We give basic laws for working with limits.

The Squeeze theorem allows us to exchange difficult functions for easy functions.

Two young mathematicians investigate the arithmetic of large and small numbers.

We want to evaluate limits where the Limit Laws do not directly apply.

We want to solve limits that have the form nonzero over zero.

Try these problems.

Two young mathematicians discuss what curves look like when one “zooms out.”

We explore functions that “shoot to infinity” at certain points in their domain.

We explore functions that behave like horizontal lines as the input grows without bound.
