The Graph of the Tangent Function

Ensino Médio::MatemáticaThe resource presents a circumference of radius 1, with center in the origin of an orthogonal cartesian system and a point that goes through the curve of the circle. On the side, the construction of the graphic of the tangent function, in radians, is shown, in the restrict interval in [0,2p], that develops according to the position of the point going through the curve of the circumferenceBasic knowledge of trigonometr
