### Flashcards
What relates a monotone function $f : [a, b] \to \mathbb R$ and integrability?::
Any monotone function is integrable.

Draw a quick picture showing the proof that a monotone function $f: [a, b] \to \mathbb R$ is integrable.::
Showing the difference between the majorants and minorants being compressed into a single stack of width $\frac{b-a}{n}$.

### Proofs
@Prove that any monotone function $f: [a, b] \to \mathbb R$ is integrable.::
Todo (analysis iii, page 16).
