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  lies in Quadrant III. , the reference angle  ' is 210  Â± 180  or 30 . Because secant and cosine are reciprocal functions and cos  is. negative in Quadrant III, it follows that sec  is also negative in Quadrant III.
