As I said, if the polynomial fit is sufficient to describe the data, you can calculate the derivative of that same polynomial using the nth derivative of a polynomial VI.

The derivative of a polynomal is just another polynomial. Given it's coefficients from the above tool, you can then calculate the derivative for any x using polynomial evaluation.

This seems trivial. Where do you have problems?

Here is what I had in mind. Makes sense?
