English: Traces cosine and sine functions from the unit circle using a single vector. The cosine value is a horizontal distance on the circle and a vertical distance on the wave. A 45 degree line graphically shows the exact translation from horizontal to vertical. If using complex math, the vertical is the imaginary axis and the horizontal is the real axis. Also when using complex math, the counter-clockwise rotating vector indicates a single positive frequency resulting in two sinusoids simultaneously. Two versions are available, "fast" and "slow".
