Figure 21-18C

Spherical coordinates in which the angles θ and φ represent the elevation (angle above the horizon) and azimuth, and r represents the radius or range.

QUESTIONS AND PROBLEMS

This is an open-book quiz. You may refer to the text in this chapter (and earlier ones, too, if you want) when figuring out the answers. Take your time! Consider all values given as exact, so you don’t have to worry about significant figures. The correct answers are in the back of the book.

1. Figure 21-19 is a graph of a straight line in the Cartesian plane. The x intercept and y intercept points are shown. Draw a graph of this curve in mathematician’s polar coordinates, substituting r for x and θ (in radians) for y. Restrict θ to the range 0 to 2π.
