Answer
Amplitude $1$, period $\pi$, see graph.
Work Step by Step
1. Rewrite the function as $y=sin2(x-\frac{\pi}{2})+2$, we can identify its amplitude as $|A|=|1|=1$ and period as $p=\frac{2\pi}{2}=\pi$
2. First graph $y=sin(x)$ (blue), shift the curve $\frac{\pi}{2}$ to the right, shrink horizontally by a factor of 2, then shift the curve 2 units up (red).
