a.
Find the quadrant for the given angle.
a.
Answer to Problem 12E
The given angle lies in the fourth quadrant.
Explanation of Solution
Given:
The given angle is
Calculation:
An angle is determined by rotating a ray (half-line) about its endpoint. The starting position of the ray is the initial side of the angle, and the position after rotation is the terminal side. In standard position, counterclockwise rotation of ray represents the positive angle and clockwise represents negative angle.
Now
Hence the given angle lies in the fourth quadrant.
b.
Find the quadrant for the given angle.
b.
Answer to Problem 12E
The given angle lies in the first quadrant.
Explanation of Solution
Given:
The given angle is
Calculation:
An angle is determined by rotating a ray (half-line) about its endpoint. The starting position of the ray is the initial side of the angle, and the position after rotation is the terminal side. In standard position, counterclockwise rotation of ray represents the positive angle and clockwise represents negative angle.
Now
Hence the given angle lies in the first quadrant.
