Determine the reference angle
WebSep 14, 2024 · A reference angle, denoted θ ^, is the positive acute angle between the terminal side of θ and the x -axis. The word reference is used because all angles can refer to QI. That is, memorization of ordered pairs is confined to QI of the unit circle. If a standard angle θ has a reference angle of 30 ˚, 45 ˚, or 60 ˚, the unit circle’s ... WebIf an angle's terminal side on the x x -axis, the reference angle is 0. If an angle's terminal side is on the y y -axis, the reference angle is \frac {\pi} {2} 2π (that is, 90^\circ 90∘ ). Otherwise, to find the reference angle: If the …
