How to get the equation of a geometric relation?
I am trying to find the relationship between the angle (Neck-Shoulder-Thumb) and [Neck-Thumb] distance.
Is there any way I can find the relation directly calculated by GeoGebra?
The question is:
(as seen in the attached image)
The Thumb is a point on the circle with a radius of 62cm, with the center point Shoulder.
The distance between Neck (0,0) and Shoulder (0,-20) is constant and 20cm.
What is the relationship between (neck-shoulder-thumb) angle and [neck-thumb] distance?
Your help is much appreciated...
