Description

The FORSIN function evaluates a Fourier sine series at a specific value .

Example

<Post_Request

    comment             = "WM-WDTM-HAVSIN-FORSIN-DIM-ACOS"

    id                  = "3"

    type                = "EXPRESSION"

    expr1               = "NULL"

    expr2               = "WM(30102010)"

    expr3               = "WDTM(30102010)"

    expr4               = "HAVSIN(TIME,1.,0.,4.,1.)"

    expr5               = "NULL"

    expr6               = "FORSIN(TIME,0.1,6.28,0.1,0.2)"

    expr7               = "DIM(TIME,1.0)"

    expr8               = "ACOS(COS(TIME))"

Arguments

The independent variable.  For example, to specify time as the independent variable, specify as TIME.

The shift in the Fourier sine series.

The fundamental frequency of the Fouries series.  It is assumed to be specified in radians per unit of unless a D is used after the value.

The constant bias term.

The coefficients for the Fourier Sine series.
