7. Graphing tangent and cotangent

Tangent Has no amplitude Period is π/(# in front of θ) Interval is Per/4 (same) HS set ( ) = 0 (same) VS number all the way in front or all the way in back separate from tan (same) Y value is 0 at 1stand 5th intervals Asymptotes – at 3rd We will not calculate 2nd and 4th Start at left point and go up towards asymptote Start at right point and go down towards asymptote You will have 2 half pieces of a tan graph

Example

Example

CoTangent Everything is the same as tangent except y values and direction y value is 0 at 3rd interval Asymptotes – at 1st and 5th intervals Goes down from left to right You will have one full piece
