Research a sinusoidal relationship that occurs in the real world. You may choose the height of the world's highest tides at The Bay of Fundy in New Brunswick, the time of the sunrise/sunset of your community, the height of a child on a swing, or your own idea. Create an algebraic model for your function and pose two questions that involve solving for the dependent variable and for the independent variable to go along with it. Select two of your classmate's problems and determine a solution, then compare your solutions with those of your classmates
