Sine and Cosine Function Values

This study guide covers the unit circle, focusing on its definition, angle measurements (radians and degrees), and trigonometric functions (sine, cosine, tangent). It explains positive and negative angles, multiple revolutions, and using the unit circle to find trigonometric values. The ASTC rule for determining the sign of trigonometric functions in different quadrants is also covered. Finally, the guide provides practice questions and tips for the exam.
