Amplitude #= a = 2#

Period # = pi / |b| = pi / 3#

Phase shift #= c / b = -135 / 3 = -45#

Vertical shift # = d = -6#

Explanation:

Use the form #y = a + cot (bx - c) + d#

To find amplitude, period and phase shift.

graph{2 cot(3x+135) -6 [-10, 10, -5, 5]}

Amplitude #= a = 2#

Period # = pi / |b| = pi / 3#

Phase shift #= c / b = -135 / 3 = -45# to the left

Vertical shift # = d = -6#
