- 1Trigonometric function
- 2The angles with different measures but with the same terminal side are called Are coterminals if their sides coincide when the angles are in standard positionCoterminal angles
- 3Is when you find the positive acute angle between the X axis and the terminal side R of the given angle The point is calledAngle of reference
- 4Depends on the quadrant in which R is locater If ø is a positive angle in standard position and the terminal side of ø is in the: Quadrant I, then ør=ø Quadrant II, then ør=180º-ø Quadrant III, then ør=ø -180º Quadrant IV, then ør=360º-øThe value of the angles of references of an angle
