The Trigonometric Circle

This page presents a comprehensive cercle trigonométrique complet, which is an essential tool for understanding trigonometric functions and their relationships. The circle is centered at the origin with a radius of 1 unit, allowing for easy visualization of sine, cosine, and tangent values for various angles.

Key features of the diagram include:

1. The circle is divided into quadrants, with special angles marked.
2. Sine and cosine values are shown for notable angles.
3. The x-axis represents cosine values, while the y-axis represents sine values.
4. Tangent values are derived from the ratio of sine to cosine.

Vocabulary: Cercle trigonométrique - A circular diagram used to visualize trigonometric functions and their relationships.

Example: For an angle of π/6 (30°), the diagram shows that sin(π/6) = 1/2 and cos(π/6) = √3/2.

Definition: The sine of an angle in the unit circle is the y-coordinate of the point where the angle's terminal side intersects the circle.

Highlight: The cercle trigonométrique tableau provides a quick reference for important trigonometric values, including those for angles 0, π/6, π/4, π/3, π/2, and their multiples.

Quote: "Valeurs à retenir" (Values to remember) - This section emphasizes the key trigonometric values that students should memorize.

The diagram also includes:

• Cercle trigonométrique cos sin tableau showing values for both sine and cosine functions.
• Cercle trigonométrique pi markings to indicate angles in radians.
• Cercle trigonométrique tangente information, derived from sine and cosine.
