The Sine Function

The tide is the regular rising or falling of the ocean's surface. This is due in large part to the gravitational forces of the moon. The following table represents water level of the tide off the coast of Kings point, N.Y., for a 24 hour period.
February 9th through February 10th of 2009.

Use your graphing calculator to produce a sine regression model for the data in the table.
Round a, b, c, and d to the nearest 0.001.

a. y = 0.519 sin(4.974 x - 3.965) + 0.812
b. y = 4.974 sin(0.519 x - 0.812) + 3.965
c. y = 0.519 sin(4.974 x - 0.812) + 3.965
d. y = 4.974 sin(0.519 x - 3.965) + 0.812
