Answer 1

Answer:

Hope this is.......irdf

Step-by-step explanation:

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. ... Like we have for the sine and cosine.
