Presentationcycloid reference point from top

The document describes a new procedure developed by Ashoka Institution for drawing a cycloid curve, which involves a rolling circle completing one revolution. The procedure divides the circumference of a circle into 12 equal parts. As the circle rolls without slipping, the successive positions of a point on the circle generate the cycloid curve. The document provides step-by-step instructions for using this procedure to draw a cycloid for a problem involving a 50mm diameter circle, and locating a point 40mm above the baseline, finding the tangent and normal to the curve at that point.
