1. Use a graphing utility to graph the polar equation shown below.
r = cos 5Î˜ + n cos Î˜, 0 â‰¤ Î˜ â‰¤ Ï€
For the integers n = -5 to n = 5. As you graph these equations, you should see the graph change shape from a heart to a bell. Write a short paragraph explaining which values of n produce the heart-shaped curves and which values of n produce the bell-shaped curves.
2. In your own words, define the term eccentricity and explain how it can be used to classify conics.
