Chapter 9: Q. 87 (page 568)

Is the street system in your town based on a rectangular coordinate system, a polar coordinate system, or some other system? Explain.

Short Answer

Expert verified

The street system in our town is based on a rectangular coordinate system.

Step by step solution

01

Step 1. Given Information 

The point r,θis the distance from the origin and angle on the unit circle in the polar coordinates.

In the rectangular coordinates, the points x,y are the distance from the xand y axes.

02

Step 2. Explaining 

As we know in the rectangular coordinate system the points are determined by their distances and in the polar coordinate system, points are determined by their angle on the unit circle and their distance from the origin. Thus, the street system is in our town is based on a rectangular coordinate system.
