To plot points in polar coordinates, we use a grid consisting of __________ centered at the pole and __________ emanating from the pole.

To fill: The description of a grid used to plot points in polar coordinates.
Answer to Problem 1E
The grid used to plot points in polar coordinates consisting of circles centered at the pole and rays emanating from the pole.
Explanation of Solution
A rectangular grid is useful for plotting points in rectangular coordinates. A grid consisting of circles centered at the pole and rays emanating from the pole as shown in below figure,
Figure (1)
From Figure (1), it is noticed that it is convenient to plot points in rectangular coordinates.
Thus, the grid used to plot points in polar coordinates consisting of circles centered at the pole and rays emanating from the pole.
