angent vertical R. 1. Show using similar triangles that tan 0 and cot 0 are the respective measures of line segments AR and BQ, which are tangent to the unit circle. (Hint: It should be clear, beforehand, that |AO| and sin 0 = |PC| = |SO|.) VE = |OB| = 1, cos 0 = |OC| = |SP| %3D %3D %3D %3D %3D 2. We have seen that for a smooth graph, the tangent lines at the stationary points are always horizontal. Ask the class if the converse is true, that is, if the tangent line at a point P is horizontal, docs it follow that P is a local extremum point? Answer: No, see point B in Example 2. m the case
