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

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

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 !

Cheers all Collabs, Jean
