FitSin[ <List of Points> ]
Calculates the regression curve in the form a + b sin(cx + d).
Example:
FitSin[{(1, 1), (2, 2), (3, 1), (4, 0), (5, 1), (6, 2)}] gives 1 + sin(1.5708x - 1.5708).
Note:
  • The list should have at least 4 points, preferably more. The list should cover at least two extremal points. The first two local extremal points should not be too different from the absolute extremal points of the curve.
  • See also FitExp Command, FitLog Command, FitPoly Command and FitPow Command.
