(a)
To find:the another way of naming the point(1,—120°)
(a)
Answer to Problem 4E
The other name for the point is
Explanation of Solution
Given information:
Consider the point:
(1,—120°)
Formula used:
The point makes 240°clockwise from the origin for ,—120.
Calculation:
Consider the point:
(1,—120°)
The point is 1 unit from the origin and makes -1200 anti-clockwise.
As seen the point makes 240°clockwise from the origin
Therefore, the other name for the point is
Conclusion:
The other name for the given point is
(b)
To find:the another way of naming the point(2,300°)
(b)
Answer to Problem 4E
The other name for the point is
Explanation of Solution
Given information:
Consider the point:
(2,300°)
Formula used:
The origin and ray makes 300°clockwise
Calculation:
Consider the point:
(2,300°)
The point is 2 units from the origin and makes 300°clockwise.
As seen the point makes -60° anticlockwise from the origin Therefore, the other name for the point is
Conclusion:
The other name for the given point is
(c)
To write: the another way of naming the point (2.5, -180°)
(c)
Answer to Problem 4E
The other name for the point is
Explanation of Solution
Given information:
Consider the point:
(2.5, -180°)
Formula used:
From the origin the ray makes -1800 anti-clockwise
Calculation:
Consider the point:
(2.5, -180°)
The point is 2.5 units from the origin and makes -1800 anti-clockwise.
As seen the point makes 180°clockwise from the origin
Therefore, the other name for the point is
Conclusion:
The other name for the given point is
