Hello, Smath gurus! That plugin or work sheet function [my preference] is missing from ages. I tried something but got red too soon. Does Smath knows other color than Red ! I guess Andrey answer is "YES". My next today [+++] is Colebrook [I have good feeling]. Cheers, Jean  Deriv Ridder.bmp (1,165kb) downloaded 50 time(s).

Hello Jean, I do not know how many times the numerical derivative like an intrinsic SMath feature has been mentioned here (quite a lot), and there is no answer yet. Why? I do not know  Regards, Ra |

Ra Hello Radovan, Guess what I guessed? I guessed your answer. Never mind Ridder. This work sheet does it as accurately. Two sets of triplets: 1. Fnct, Deriv, Cumul 2. linterp(data,x), ainterp(data,x), cinterp(data,x) Where data will be either F, D, Σ Where user enters Project(f,L,H,N) f => function name L => low limit H => high limit N => number of points Well, Smath does not understnd much of languages, but codes !
