As below.

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

#"Given : " y = - cot (4pix)#

#A = -1, B = 4pi, C = D = 0#

#"Amplitude " = |A| = color(crimson)("NONE ") " for cotangent"#

#"Period " = pi / |B| = pi / (4 pi) = 1/4#

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

#"Vertical Shift " = D = 0#

graph{- cot (4pix) [-10, 10, -5, 5]}
