Question: 1. The desert temperature, H, oscillates daily between 40°F at 5 am and 80?F at 5 pm. Write a possible formula for H in terms of t, measured in hours from 5 am.
2. The depth of water in a tank oscillates sinusoidally once every 6 hours. If the smallest depth is 5.5 feet and the largest depth is 8.5 feet, find a possible formula for the depth in terms of time in hours.
