# Interactive video lesson plan for: Water Depth Word Problem Modeled with Cosine Sine Function

#### Activity overview:

Analyzing the time between high tides and the depth of the water, I make a function that models the tides and then calculate the safe hours for a ship to enter the port.

At minute 13:27 I wrote the inverse cosine of .667 or arccos(.667), that should be arccos(-.667). Find free review test, useful notes and more at http://www.mathplane.com
