The quadrantal family: angles belonging to this family must be coterminal family of angles: angles belonging to this family must be coterminal with. Example 1: each of the given angles belongs to one of the four families of special angles. Determine the family of angles for which it belongs. family of angles: angles belonging to this family must be coterminal with family of angles: angles belonging to this family must be coterminal with. Understanding the definition of the trigonometric functions of general angles. Definition: let be an angle in standard position and let. 2 y is the distance from the origin to the point then y= sin r csc r y y. 0 sec = _________ cot = _________ tan = _________ cos = _________ Example 2: find the exact value of the six trigonometric functions of a positive angle if (1, -2) is a point on its terminal side. sin = _________ csc = _________
