You can put this solution on YOUR website! Please explain how to Find the amplitude, period, vertical translation, and any phase shift for this function:
y = (-1/2)sin((1/2)x+pi)
***
Form of equation for sin function: y=-Asin(Bx-C)+D, A=amplitude, period=2π/B, phase shift=C/B, D=vertical shift.
For given sin function:y = (-1/2)sin((1/2)x+pi)
amplitude=1/2
B=1/2
period=2π/B=2π/(1/2)=4π
C=π
phase shift=C/B=π/(1/2)=2π
translation: curve is reflected about the x axis
vertical shift: none
