FitSin[ <List of Points> ]
Calculates the regression curve in the form a + b sin(cx + d).
Example:
FitSin[{(0, 1), (2, 4)}] gives '.
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.
