Find amplitude, period, PS, VS. then graph.

$y=\cos\left(x+\dfrac{\pi}{2}\right)$For the graphs of $y=A\sin(\omega x - \phi)$ or $y=A\cos(\omega x - \phi),\omega>0$

Amplitude $=|A|$

Period $T=\dfrac{2\pi}{\omega}=\dfrac{2\pi}{2}=\pi$

PS $=\dfrac{\phi}{\omega}=\dfrac{\pi}{4}$

well so far

I don't know what the greek letter is for VS or Vertical Shift? which is usually D
