1. Trigonometric Function
2. Describe two real-world situations that could be modelled by a trigonometric function. Cannot be Ferris Wheel ride, tides, hours of daylight. Cite any Internet source you may have used for reference.
3. Clearly define all variables in the relationship.
4. Clearly justify why this model fits the real applications with specific reference to key features of the function.
5. Your justification should also include reference to the graphical and algebraic models.
