Ciclo Trigonométrico, ou círculo trigonométrico, ou circunferência trigonométrica.

One of the most important and ever-present concepts in all areas of science is the Trigonometric Circle. It is a mathematical tool that allows us to understand the sine, cosine, and tangent of all angles of a circle. And the concept of a circle allows us to understand that the values ​​repeat cyclically. In physics, it is widely used in wave phenomena, but its concept is present in all scientific subjects. In this video, we present the basic concept of how the trigonometric circle works. The angles in this video are described in degrees; we have not yet worked with radians, which will be the topic of future lessons. Happy studying. =========== Bibliographic Reference de SOUSA, Airtonelton Magalhães CURRICULUM OF TRIGONOMETRY IN HIGH SCHOOL: AN ANALYSIS IN OFFICIAL DOCUMENTS, PNLD AND ENEM.
