Trigonometry via constructive geometry and SVG
This is a series of screenshots primarily for the benefit of the students in the course this summer.
I began the unit by rolling a large wheel, keeping track of both the linear distance and dividing by the radius to produce an angular measure.
The next day I moved into constructive geometry and SVG diagrams as a way to deliver the basic trignometric functions.
The goal was to draw a square circumscribed in a circle using SVG.
The next day the focus shifted from 45 degrees to a 30-60-90 triangle via trying to inscribe an equilateral triangle in a circle using SVG.
The homework was to generate the two triangles seen in the lower right corner above. The solutions are worked out below.
