Math Problem Statement
so a figure with an angle of 300 degrees on a circle in standard position
Solution
A figure with an angle of 300 degrees in standard position on a circle is described as follows:
-
Initial Point: The angle starts at the positive -axis, which is the standard reference line for angles in standard position.
-
Direction of Rotation: Since the angle is positive, the rotation is counterclockwise from the positive -axis.
-
Magnitude of Rotation: A full circle corresponds to , so an angle of means you rotate counterclockwise from the positive -axis by 300 degrees, which is 60 degrees short of a full circle.
-
Reference Angle: The reference angle, which is the acute angle formed with the nearest axis (here the -axis), is .
-
Quadrant: Since is between and , the terminal side of the angle lies in the fourth quadrant.
-
Coordinates of the Terminal Side: The terminal side intersects the unit circle. For an angle of , the corresponding coordinates on the unit circle are: These values represent the cosine and sine of the angle, respectively.
Summary:
- Quadrant: Fourth quadrant
- Reference Angle:
- Coordinates on Unit Circle:
