One Cycle Tells You All of Them

You'll learnto read the period, the midline and the amplitude straight off a repeating graph.

A tide gauge at a dock falls to 3 m, climbs to 11 m, and falls back again, all day long. Measure one cycle of that and you know the depth at every hour, tomorrow included. Twelve short steps; press Next for each one.

measure one cycle, and you know every other one
Before you start
What you're looking at
A graph of the water depth at a dock, hour by hour, for one whole day.
The question
How long is one repeat, and how do you measure it without halving it by mistake?
