In this animation, we see what the “polygonal sine” looks like for [the square, the hexagon, the triangle and the heart. The polygon is such that the inscribed circle has radius 1. We’ll ...

Part of that is the way it's taught. Students are taught the "unit circle" and its relationship to trigonometry, but many fail to make the leap on how crucial circles are for trig functions.

It’s a computer animation by computer artist Daniel Sierra ... He was inspired by the motion of sine waves, upon which he built a tapestry of color and sound: The concept of universal building ...

This circle has the centre at the origin and a radius of 1 unit. The point P can move around the circumference of the circle. At point P the \(x\)-coordinate is \(\cos{\theta}\) and the \(y ...
