dear Mr ,
You have an equation with 3 unknown parameters (a, b and c).
Take 3 values of your measurements.
Then you have 3 equations with 3 unknown parameters and those should be solved.
Repeat this procedure several times for different values of S and average the results for a, b, and c.
Otherwise, plot your data in a spreadsheet and use the regression line feature.
success

dear Mr ,
If you have 5 unknowns. then you need 5 equations to solve the unknowns.
(If you can find a mathematical relationship)
keep on trying

Curve Fitting
Hi,
I need to calculate the parameters of the following equation:
S = (a + ((b-a)/(1+((2*pi*x)^2*c^2))))
I have the measured data of S and need the parameters a,b and c to get a curve fit in the software for analysis.
If someone can help me in this regard or suggest any software that can perform this thing for me?
Thanks ■
