Sine and cosine represent the movements you need to draw a unit circle (with a two axis plotter). It is unfortunate if we don't introduce them like that.https://twitter.com/ThingsWork/status/1089272107119325185 …

Is there a way to visualize a sphere instead of a circle ?

There are many. The most popular one adds a third function to vary the size of circles along an axis (so you get a globe). In our world, most spheres describe the equidistant boundary of a region around a point (for instance, a shock wave).

The nicest I know works by creating a flat space filling curve or a flat lattice and then shorten some of the distances in regular intervals to induce positive curvature, so the lattice rolls itself up into a ball.

If you add links that connect points that are not adjacent in 2D, you create a 3rd dimension. If you don't overdo it, this will just be a curved 2D space. If you add more links over longer distances, the 2D space can fold into a full 3D space. It also works for going to 4D.

“more links over higher distances” leads to “folding up into higher dimensions”. Dude. Prose, not poetry.
