Chapter 9: Q. 21 (page 583)

Transform each polar equation to an equation in rectangular coordinates. Then identify and graph the equation. Verify your graph using a graphing utility.

r=2cos胃

Short Answer

Expert verified

The graph is

Step by step solution

01

Step 1. Given information

The given polar equation isr=2cos胃

02

Step 2. Convert polar equation into rectangular equation and graph it.

r=2cos胃r2=2rcos胃

As x=rcos胃and r2=x2+y2

So,

x2+y2=2xx2+y2-2x+1=1(x-1)2+y2=1

Then, the graph is
