As seen below.

#y = (-) cot (pi x) #

Standard form of cotangent function is #y = A cot(Bx - C) + D#

#A = -1, B = pi, C = D = 0#

#Amplitude = |A| = "NONE for cotangent function"#

#"Period " = (pi) / |B| = pi / pi = 1 #

#"Phase Shift " = -C / B = 0#

#"Vertical Shift " = D =0#

graph{- cot(pix) [-10, 10, -5, 5]}
