Source sentences:
text: We know the lowest point is at 5 minutes, and the period is 20 minutes, we can figure out that the highest point is at half the distance of the period (10 minutes) from that lowest point.
text: it’s period is about 20 minutes, and it’s normal depth is 10 meters.
text: We are already given the amplitude (12 meters), vertical shift (normal depth is at 10 meters), and period (20 minutes), so \(\displaystyle b=\frac{2\pi }{\text{new period}}=\frac{2\pi }{20}=\frac{\pi }{10}\).
