FORSIN

The FORSIN(x,x0,ω,a0,…,an) evaluates a Fourier sine series.

Format

FORSIN(x,x0,ω,a0,…,an)

Arguments

x

The independent variable.

You can enter a valid expression for the independent variable such as 2*TIME.

x0

The constant offset of the independent variable.

ω

The fundamental frequency of the series in radians per unit of the independent variable.

Append a D to the value to specify the frequency in degrees per unit of the independent variable.

a0,…,an

A set of real variables specifying an nth order Fourier series for n<30.

You can define up to a 31 coefficients.

Function Definition

FORSIN(x,x0,ω,a0,…,an) = 
     a0 + Σj=1 … n aj*Tj(x-x0)
where
     Tj(x-x0) = sin{j*ω*(x-x0))
