This is an experiment to test myself: Using only my knowlege of trigonometry and the unit circle, can I implement trigonometric functions?
The degree value is analyzed to determine what quadrant it's in. The angle's "progress" through the quadrant
(0 - 90 degrees) is expressed as a value between 0 and 1 (or -1 and 0, depending on the quadrant), which is then used
to approximate X and Y coordinates.
These coordinates are then scaled to an arbitrary radius length (the higher, the more accurate) and then normalised
