I guess I can get as far as doing the phase shift but I don't know what to do with the 2 in front of the x \[y=sin(2(x\pi/2))\]dw:1360883459233:dw

the phase shift is pi/2 isn't it?

\[\sin(\pi)=0\]so the graph should start at x=0, y=0

a phase shift of pi will shift the graph a halfperiod to the right, which for the sin is equivalent to turning it upsidedown

Oh i see. so the phase shift is pi and not pi/2

right, you could also see that by applying\[\sin(\alpha+\beta)=\sin\alpha\cos\beta+\cos\alpha\sin\beta\]
