Math Problem Statement
draw the angle in standard position: - 3pi/4
Solution
To draw the angle in standard position:
-
Standard position: The initial side of the angle lies along the positive -axis, and the terminal side is determined by rotating counterclockwise (for positive angles) or clockwise (for negative angles).
-
radians: This angle is negative, so we rotate clockwise from the positive -axis. In radians, represents a half-circle (180°).
- is , or three-quarters of the way to (which is ).
-
Position of the angle: Start from the positive -axis and rotate clockwise by 135°. The terminal side of the angle will lie in Quadrant III, as you have passed 90° (which lands in Quadrant IV) but stopped before reaching 180° (which lands on the negative -axis).
The terminal side should end between the negative -axis and the negative -axis.
