Hi,
I have a set of {x,y} data points:
{{0.03512, 0.5}, {0.0351181, 0.499}, ... {0.113972, 0.699}, {0.115072, 0.7}}
These data points look like a function y=f(x) when plotted on the xy axes. However, I do not know what the function f(x) is. But I need to get the approximate derivative df/dx, as another set of data points. How can one use Mathematica to do this?
Thanks,
Michael
