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.
Sine, Cosine and Tangent are all based on a Right-Angled Triangle. Before getting stuck into the functions, it helps to give a name to each side of a right triangle:  1 Opposite is opposite to the angle Î¸.  2 Adjacent is adjacent (next to) to the angle Î¸.  3 Hypotenuse is the long one.n this animation the hypotenuse is 1, making the Unit Circle. Notice that the adjacent side and opposite side can be positive or negative, which makes the sine, cosine and tangent change between positive and negative values also.
