Webbthe three primary trig ratios which is positive is sin θ.We will come back to this result shortly. Example 2 An angle θin standard position has the point Q(–12,–5) on its … WebbIt is evident that a trigonometric function has the same value for all coterminal angles. When n is an integer, therefore, sin ( A ± 360 n) = sin A; there are similar relations for the other five functions. These results may be expressed by saying that the trigonometric functions are periodic and have a period of 360° or 180°. WebbOne side of the angle is always fixed along the positive x-axis - that is, going to the right along the axis in the 3 o'clock direction (line BC). This is called the initial side of the … red arc quilter
