    Translations of sine and cosine functions?

    Can anyone help me graph this function?
    y= sin(2 angle+pi)
    I know the amplitude is 1
    the period seems to be 2pi/2= 1 pi
    and the phase shift is -c/k which is -pi/2
    I am unsure how to graph this however

    y= sin(2 angle+pi)=-sin(2angle)

    Actually I think I solved it

    my graph has (-pi/2,0)
    (pi/4,1)
    (0,0)
    (pi/4,-1)
    (pi/2,0)
