Thread: tracking direction of movement

Hi, image a circle, place your index finger on the circle at say 1 o'clock and start to rotate your finger clockwise to 3 o'clock.

Now without taking your finger off the circle start to rotate your finger back through 2, 1 ,12 11 to 10 anti clockwise.

Is there a way, (sine wave has been suggested), to be able to determine where on the circle your finger is and in what direction it is moving?

Thanks

As far as I know, with the information you gave, there is no way to where your finger is. The reason for this is because in order to plot a graph, you need two variables. In the information you have, there is only one variable - the location of your finger. Without something to compare it to (such as the time or the speed you are moving your finger) there is no way to know exactly where your finger is at any given time.

Bums

back to the drawing board!

Thanks
