To plot: the points and two other polar coordinates.
Answer to Problem 14E
Here, the two polar coordinates of the point are one with
Explanation of Solution
Given:
Calculation:
plot the point that has the given polar coordinates.
given the plot in
This point is
This red dot is the plot of the point
Given two other polar coordinate representations of the point, one with
The first formula is true because angles that are separated by multiples of
Let’s apply these formulas to the point
For the polar coordinates equivalent with
Conclusion:
Therefore, the two polar coordinates of the point are one with
