Hi, I have some data, to which I am fitting a polynomial of degree 4.
In[112]:= funkcija = Fit[tocke, {1, x, x^2, x^3, x^4}, x]
Out[112]= 7655.48 - 1.37747*10^-16 x - 0.0000580449 x^2 +
1.0626*10^-23 x^3 - 8.35914*10^-13 x^4
Now what I need is actually derivative of this polynomial and I don't want to manually rewrite each coefficient, or is that really necessary?
In the end I am interested into values of the derivative in points from my first column of the imported data.
