- FitSin[ <List of Points> ]
- Calculates the regression curve in the form a + b sin(cx + d).
- Example:
FitSin[{(0, 1), (2, 4)}]gives ℯ0.69x.
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 FitLog Command, FitPoly Command, FitPow Command and FitSin Command.
CAS Syntax
- FitSin[ <List of Points> ]
- Calculates the regression curve in the form a + b sin(cx + d).
- Example:
FitSin[{(0, 4), (1, 0), (2, -4), (3, 0)}]gives ℯ0.69x.
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 FitLog Command, FitPoly Command, FitPow Command and FitSin Command.
