Tangent Function
Tangent Function-
y = tan (x)
one cycle occurs between -/2 and /2
There are vertical aymptotes at each end of the cycle. The asymptote that occurs at/2 repeats every units.
amplitude: none, graphs go on forever in vertical directions
The Graph-
represents y = tan (x)
The graph does not STOP even though the plot may "appear" as if the graph stops as the y- values increase/ decrease
