```Simon,

Look up Interpolation (and the associated functions) in Help. Make an
InterpolatingFunction from your data and then you can differentiate and
integrate that.

Dear Everyone,
When a function is a data list: f[x]={ {x1, f1}, {x2, f2}, {x3, f3},
... }
Which built-in function was used to Integrate or Differentiate the
function f[x], or function such as x*f[x] / (x^2 - x0^2)   ?
Thank you very much!
Simon
