Work Step by Step
Step 1. Rewrite the function as $y=sin2(x+\frac{\pi}{4})$
Step 2. Using transformation, start from $y=sin(x)$ and first shift the curve left by $\frac{\pi}{4}$; then shrink horizontally by a factor of 2 to obtain the red curve.
Step 3. Present the curve over the interval $[0,2\pi]$ as shown in the figure.
