Unit Circle (Trigonometric)
Giáo dục | 189.1KB
The unit circle or trigonometric circle is a circle whose center is located at the origin of the Cartesian plane and its radius is 1 (one). It is used in the study of trigonometric functions such as sine, cosine and tangent.
- Understand how the projections of the arcs sine, cosine and tangent work in the unit circle (or trigonometric circle);
- Why the values of sine and cosine are limited to -1 and +1;
- Why the tangent of 90 ° and 270 ° are not defined
- When and where the values of the trigonometric ratios (sine, cosine, tangent) are positive, negative, zero or null;
