Cardioid Graph. Polar equation of the common cardioid is ra 1cos theta r a1 cosθ. The shape is traced by two circles placed edge to edge and one circle moves around the circumference of the other without slipping.
Mathematically it is given by the polar equation r a1 cosθ at times also written as r 2a1 cosθ It appears as shown below. R-3-3cos Noticably the graph is reflected around the y-axis from when ab3. Constructing a cardioid on a polar graph is done using equations.
A cardioid is a special case of limacon.
A cardioid is a two-dimensional plane figure that has a heart-shaped curve. In this video I will graph polar equation r22sintheta the cardioid. Rcos 2 theta Four Leaf Rose. Technically speaking a cardioid shape can be created by following the path of.
