To find: The polar equation of a passenger car.
a.

Answer to Problem 128E
The polar equation of a passenger car is
Explanation of Solution
Given information:
The center of a Ferris wheel lies at the pole of the polar
Calculation:
The Ferris wheel is a circular frame of radius
Therefore, the polar equation of a passenger car is
b.
To find: The interpretation of the coordinates after
b.

Answer to Problem 128E
The interpret their coordinates after
Explanation of Solution
Given information:
The center of a Ferris wheel lies at the pole of the polar coordinate system.
Calculation:
The car in the Ferris wheel starting from the ground level located at
This implies that car would have moved through an angle
The Ferris wheel showing the starting point and the location of passenger’s car after rotation for
Figure (1)
Therefore, the interpret their coordinates after
c.
To find:Convert the point in part (b) to rectangular coordinates.
c.

Answer to Problem 128E
The rectangular coordinates is
Explanation of Solution
Given information:
The center of a Ferris wheel lies at the pole of the polar coordinate system.
Calculation:
The relation between rectangular and polar coordinates.
Calculate the rectangular coordinates of the point
The point
This means that after
Therefore, the rectangular coordinates is
