File:Sine curve drawing animation.gif

Description The relation between the sine curve and the unit circle is illustrated in this animation. As the angle increases, the value of the sine traces the familiar sine curve, in red. Here, the angle in radians is represented by the blue arc around the circle and the blue line, both of which have the exact same length.
