#### DESCRIPTION:

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 ââof sine and cosine are limited to -1 and +1; - Why the tangent of 90 Â° and 270 Â° are not defined - When and where the values ââof the trigonometric ratios (sine, cosine, tangent) are positive, nega
