Chapter 14.1, Problem 19WE

To determine

To find: The North Pole $\left(\text{Point}N\right)$ have an image.

Answer to Problem 19WE

The North Pole $\left(\text{Point}N\right)$ does not have an image.

Explanation of Solution

Given information:

It is given that a piece of paper is wrapped around a globe of earth to form a cylinder as shown. $O$ is the center of the earth and a point $P$ of the globe is projected along $\overline{OP}$ to a point $P\text{'}$ of the cylinder

  

Calculation:

As the piece of paper in a circle form, the top of the cylinder is open. Therefore, the point $N$ of the globe cannot leave image.

Therefore, the North Pole $\left(\text{Point}N\right)$ does not have an image.
