A Challenging Problem of 2-D Geometry for Computation of Eccentricity by HCR
An observer is viewing a circular plane AB, with a radius OA=OB=25 units & the center O, from a point P (eye of observer) at a distance PO=70 units from the center O such that the angle between normal to the plane (at the center O) & the line PO joining the given point P to the center O of circular plane is 30 degree. But it appears to the observers as an elliptical plane A'B having eccentricity e & the center O'. (As shown in the diagram)
Find out the value of e
The answer is 0.666024046.
