Cardioid Circle Graph. This graph is obtained by tracing out the path of a circle rolling over another fixed circle. The point of the cardioid is at 00 with the graph being symmetric about the x-axis.
Look at the graph of. When the value of a equals the value of b the graph is a special case of the limacon. Circle with length 6 facing left.
We attempt to find points of intersection.
1 2 cost cos2t 2sint sin2t The equation of a cardioid. There is one cusp in the cardioid. The cardioid is formed by following the path of a point on a rolling circle over another fixed circle of the same radius. To find the area between the curves you need to know the points of.
