The unit circle definition is tan(theta)=y/x or tan(theta)=sin(theta)/cos(theta). The tangent function is negative whenever sine or cosine, but not both, are negative: the second and fourth quadrants. Tangent is also equal to the slope of the terminal side. tangent right triangle trigonometry the unit circle.
Because the terminal side of 315  lies in Quadrant IV, the reference. angle  ' is 360  Ã­ 315  or 45 . Because tangent and cotangent are reciprocal functions and tan  is negative in. Quadrant IV, it follows that cot  is also negative in Quadrant IV.
