The shape of a limacon can be defined parametrically as                                    r = r0 + cos θ,                                    x = r cos θ,                                    y = r sin θ. When r0 = 1, this curve is called a cardioid. Use this definition to plot the shape of a limacon for r0 = 0.8, r0 = 1.0, and r0 = 1.2. Be sure to use enough points that the curve is closed and appears smooth (except for the cusp in the cardioid). Use a legend to identify which curve is which.  use phyton language  import math import numpy as np import matplotlib.pyplot as plt %matplotlib inline

Question
  1. The shape of a limacon can be defined parametrically as

                                   r = r0 + cos θ,

                                   x = r cos θ,

                                   y = r sin θ.

When r0 = 1, this curve is called a cardioid. Use this definition to plot the shape of a limacon for r0 = 0.8, r0 = 1.0, and r0 = 1.2. Be sure to use enough points that the curve is closed and appears smooth (except for the cusp in the cardioid). Use a legend to identify which curve is which.
