y = tan x
Tangent Graphs:
** No amplitude y = a tan bx
π
** Period is b
** Split period in half and mark off
on both sides of y­axis, then draw the asymptotes at these points
** Plot (0, 0)
** Plot "a" at 1/4 point to right of y­axis

y = cot x
Cotangent Graphs:
** No amplitude ** Period is
y = a cot bx
π
b
** Label period to right of y­axis. ** Draw asymptotes at beginning and end. ** Plot x­intercept at halfway point of period
** Plot "a" at 1/4 point to right of y­axis
