Infinite Continued Fractions

In this article we are going to look at infinite continued fractions - continued fractions that do not terminate.

To sketch the graphs, consider whether the functions are odd or even and consider values of the functions for $x=0$ and for very large $x$. Confirm your sketch by differentiating the functions and finding the turning points.

To prove the hyperbolic trig identities requires only some simple algebra.
