As below.

Standard form a sine function is #y = A sin (Bx - C) + D#

#"Given " y = sin (theta - 180^@) = sin (theta - pi^c)#

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

#Amplitude = |A| = 1#

#"Period ' = (2pi) / |B| = (2pi)#

#"Phase Shift " = -C / B = -pi / 1 = -pi, " "color(crimson)( pi " to the LEFT"#

#"Vertical Shift " = D = 0#
