Problem: Create a Sine function for a beach of your choice. Explain the components of the model, compare the predictions from your model to the actual values from the data and include a use of tide model.

Chart:

__ Equation: __ f(x)=2.6*sin(.4x+ -2.7)+3.2

Components of the model:

Amplitude: 2.6 Period: 15.7 Horizontal Shift: -2.7 (right) Vertical Shift: 3.2

Predictions: We were suppose to use a "x" value that was on the chart and plug it into our equation to see if it matches or is near the actual "y" value.

Predicted value: Actual Value: x=3:30 y=3.14 x=3.30 y= 2.1

Practical Use:

Surfing, Swimming, and when you can move your beach chairs close to the water !!
