curve fitting

[baffled]

I have some data that I wish to fit to a curve in the form of a/(x^4+bx^2+c). What is my best approach?

Hi,
you can do it in following way:
1. As initial data you have two arrays {Xi} and {Yi}
2. Calculate {Ti}={Xi*Xi}
3. Calculate {Zi}={1/Yi}
4. Make the polynomial fit (Functions->Mathematics->Curve fitting->General polynomial fit.vi) of second order for points {Ti,Zi}
5. You will get your coefficients (I hope).

Good luck.
