Label the quadrants where the trig ratios are positive.
Quadrant I: sin, cos, tan, cot, sec, csc Quadrant II: sin, cscQuadrant III: tan, cotQuadrant IV: cos, sec
What is the initial side of a circle when dealing with degrees?
Initial side is the side where the rotation angle starts, located on the positive x-axis, and it is also referred to as 0.
What is the difference between positive angles and negative angles?
Positive angles are angles that go counter-clockwise from 0 degrees. Negative angles are angles that go clockwise from 0 degrees.
