# Comparing Graphs In Exercises 27-30, use a graphing utility to graph the conic. Describe bow the graph differs from the graph in the indicated exercise. r = 4 1 + cos ( θ − π / 3 ) (See Exercise 16.)

To determine

To Graph: The conic r=41+cos(θπ3) using a graphing utility and explain how the graphs differ from the graph in indicated exercise.

Explanation

Given:

The provided polar equation is r=41+cos(θπ3)(See exercise 16).

Graph: Use Ti83 graphing calculator to sketch graph of the polar equations. The following steps are followed.

Step 1. Press ‘MODE’ button.

Step 2. Go to ‘Func’ and choose ‘Pol’.

Step 3. Press ‘Y=’ button and write r1=41+cos(θπ3)

Step 4. Press ‘GRAPH’ button.

And the required graph is shown below:
