# Graphing a Polar Equation In Exercises 45-54, use a graphing utility to graph the polar equation. Find an interval for θ over which the graph is traced only once. r = 3 ( 1 − 4 cos θ )

To determine

To Graph:

The polar equation r=3(14cosθ) by the graphing utility & then find an interval for θ over which the graph is traced only once.

Explanation

Graph: The Ti-83 calculator steps to plot the graph:

Step1: Press MODE Key and select POL mode.

Step2: Press (Y=) button.

Step3: Type the function r1=3(14cosθ)

Step4: Now press the (GRAPH) key and the graph is obtained.

The graph of polar equation is shown as below:

Calculation:

If θ=0r=9

If θ=π2r=3

If θ=πr=15

If θ=
