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.
The Second Quadrant. In the second quadrant, \(x\) is negative but \(y\) and \(r\) are both positive. Hence, the two ratios involving \(x\) (cosine and tangent) are negative but the sine is positive. However, it is possible to find the exact values of these ratios in the second quadrant.he Third Quadrant. In the third quadrant, \(x\) is negative as is \(y\) but \(r\) is positive. Hence \(\sin \theta\) and \(\cos \theta\) are negative but \(\tan \theta\), which is the ratio of two negative quantities, is positive. Once more, it is possible to find the exact values of these ratios in the third quadrant.
