The FORSIN function returns the results of the coefficients and variables evaluated in a Fourier sine series.
Format
Arguments definition
|
|
The input variable for the defined Fourier sine series •Generally, this variable is time or a function that results a real number. |
|
|
The x-direction offset for the variable (x) in the Fourier sine series |
|
|
The base frequency for the Fourier sine series (in radians) |
|
|
The coefficient values in the Fourier cosine series that calculates the linear superposition in line with the Fourier cosine series •These values are defined by the number of input coefficients and can include up to 31 coefficients. |
Formulation
Example
FORSIN(time, 0.25, 180D, 0, 1, 2, 3)
•x = time: Independent variable
•x0 = 0.25: Shift in the Fourier sine series
•
= 
: Frequency of the sine
series
•a0, a1, a2, a3: Define coefficient for the sine series
•a0 =0, a1 =1, a2 =2, a3 =3
