This document provides an introduction to trigonometric graphs. It discusses that the sine graph plots the y-coordinate of a point P on the unit circle against the angle Theta. It also covers the graphs of the sine and cosine curves, key points in these graphs, and the anatomy of a trig function including amplitude, cycles, phase shift, and vertical shift. Exercises are provided to practice these concepts.

3. Unit Circle The sine graph plots Theta vs. the y-coordinate of point P

5. Section 6.4 Graph of Sine Curve

6. Section 6.4: Graph of Cosine Curve

7. Section 6.4: Key Points in the Sine and Cosine Curves

8. Anatomy of the Trig Function a - amplitude (half of the distance between the minimum and maximum of the graph) b - cycles (the number of times within 2 π the graph repeats. The period is determined by dividing 2 π by b ) c - phase shift (horizontal shift of the starting point of the graph) d - vertical shift of the mid-line of the graph
