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