Thread: 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)
