At that time you find that depth of the water at the end of the pier is 1.5 m. Assume the depth of the water varies sinusoidally with time. Explain the meaning of the parameters a, b, c, and d in the model. As an extension, students can research the connection between tidal flow and models for predictions of global warming. In 1990, scientists estimated that a total of 4 million pounds of debris was in Earth orbit.
Students investigate doubling time for each of the models.
