Part III Use your findings in Part II to label each angle on your unit circle in Part I with appropriate coordinates. Part IV Trigonometric functions are defined in this way. Given that P is a point on the terminal side of a position angle with coordinates (x, y) and r is Ѳ the distance from the origin to P, the six trigonometric functions are: sine sin = y cosine cos = x tangent tan = y Ѳ Ѳ Ѳ r r x Cosecant csc = r secant sec = r cotangent cot = x Ѳ Ѳ Ѳ y y y Use these definitions to find the six trigonometric functions of each of the 16 angles in your circle. Record your answers in the given chart. Part V Look for patterns in your chart. Describe at least three different patterns that you can see.
