Concept explainers
To find: the terminal point made by different angle given below.
Answer to Problem 33E
Explanation of Solution
Given:
Concept used:
Terminal point:
The angle made by the end point with nearest horizontal x-axis or the reference plane.
For a unit circle:
In 1st quadrant all trigonometry ratios are positive.
In 2nd quadrant only
In 3rd quadrant only
In 4th quadrant only
Calculation:
Adding or subtracting multiples of
The reference number is given by
Since the terminal point t is in the quadrant 1ST.
For a unit circle:
In 2nd quadrant
Since the point lies in 3rd quadrant where
Since the point lies in 1st quadrant where
Hence,
