Monotonic Sequences

Example:

Keeps peaking--longer and shallower each time.

Monotonic sequences are much nicer.

Try my cool new interactive demonstration on monotonic sequences!!

In fact, even more is true.

What's cool about this theorem: You don't need to know what the sequence converges to, to show that it does converge.

Proof.

Example:

Claim:

Proof.

Claim:

Proof.

We have now proved that x_n is increasing and bounded. Thus, x_n converges. But, what is the limit of our sequence x_n?
