negative angles
Angles generated by clockwise rotation.
Negative angles are basically the measurement of an angle in the opposite direction of what is considered positive. In the standard position of an angle, a positive angle is measured counterclockwise from the positive x-axis. Negative angles, on the other hand, are measured clockwise from the positive x-axis.
For example, a positive angle of 60 degrees is measured by starting at the positive x-axis and moving counterclockwise by 60 degrees. On the other hand, a negative angle of -60 degrees is measured by starting at the positive x-axis and moving clockwise by 60 degrees.
Negative angles can also be written in radians, which is the standard measure for angles in calculus and other advanced branches of mathematics. A negative angle in radians is measured by starting from the positive x-axis and moving clockwise, just like in degrees.
One common use of negative angles is in trigonometry, where angles may need to be measured in any quadrant of the unit circle, which includes negative angles. Another application is in physics, where negative angles can be used to represent the direction of rotation or movement in a system. Overall, negative angles are an important concept in mathematics and its various applications.
