See double-cycle graph.

#y = 1/3 tan x = 1/3 (sin x/cos x),#

#x ne# ( zero of denominator ) #kpi, k = 0, 1, +-2, +-3, ...#.

Tthe period of #oo#-arm tan wave #= pi#.

Amplitude of a wave of infinite length, about the axis y = 0 is pi/2.

x-intercepts ( zeros of the numerator )#

# x = ( 2 k + 1 )pi/2, k = 0, +-1, +-2, +-3, ...#

See #oo#-arm tan waves, for two cycles, between ( asymptotic )

#x = +- pi#. , .
