Question
Sketch the graphs of the following function: $\psi\text{(x)}=4\sin3\Big(\text{x}-\frac{\pi}{4}\Big),0\leq\text{x}\leq2\pi$
✓
Answer
$\psi\text{(x)}=4\sin3\Big(\text{x}-\frac{\pi}{4}\Big),0\leq\text{x}\leq2\pi$
| $\text{x}$ | $\frac{\pi}{4}$ | $\frac{7\pi}{12}$ |
| $\psi\text{(x)}=4\sin3\Big(\text{x}-\frac{\pi}{4}\Big)$ | $0$ | $0$ |
