Squine and Cosquine (VIDEO!)

Ordinary sine and cosine plot the height and “overness” of a star as it moves about a (presumed) circular path in the heavens. But what if we assumed instead that stars followed square paths overhead?!

In this video we plot the graphs of squine and cosquine – just for fun! (Though I would argue to high-school teachers that there is also very good pedogogical value for doing this with students!)

    Written for educators - and their students too! - this website, slowly growing, takes all the content Tanton has developed in his books, videos, and workshops, and organizes it into short, self-contained, and complete, curriculum units proving that mathematics, at all points of the school curriculum, can be joyous, fresh, innovative, rich, deep-thinking, and devoid of any rote doing! Let's teach generations of students to be self-reliant thinkers, willing to flail and to use their common sense to "nut their way" through challenges, to assess and judge results, and to adjust actions to find success. (Great life skills!)
