TITLE

The graph of sin x

ANIMATION:

Looped animation of the radius rotating anti-clockwise. As it does, so the angle at the centre is swept out and the line from the end of the radius perpendicular to the centre line changes accordingly - it as if it is sliding along the marked centre line, getting longer and shorter as it goes. When it has made a complete turn, the angle at the centre 'resets' and starts sweeping out again.
