A Surreptitious Sequence: The Catalan Numbers

About

f22 produces online videos for the Mathematical Association of America. The videos showcase a short lesson by professors from around the US. f22 strives to recreate the "classroom" atmosphere for these professors in order for them to feel most comfortable and natural on camera. In post production, our graphic team uses graphic visuals and animations to enhance the visual experience for the viewer and to aid the professor's material.

Here is a clip from a recent recording with Alissa S. Crans, Associate Professor of Mathematics at Loyola Marymount University.
