anticipate Logarithmus with suitor Base "LOG(Wert;Basis)" missing

 

Lefty
Hi Profis, I have there a problem.
Profan 11
I take with of/ one Kamera slanting of supra a way on (Bowlingbahn)
now have I a Wertetabelle prepares with Pixeln and moreover gehörigen real Coordinates. Anhand this values have I then in Exel a function prepares The me The Coordinates so errechnet, the The theory with geringem Error nachgebildet becomes.

in the Exel-File is : slot A The Pixel
slot B the theoretical Result
slot C my best approach with the LOG trouble
slot D fully wrong
slot E bester attempt of my son (Informatiker)

After many try with iterativer Spielerei I get the following Result

A2/($G$2+LOG((A2/$G$3+$G$4);$G$5))/$G$6+$G$7

The problematische part this function is : LOG(A;X) where A the Pixelwert and X The Base is.
unfortunately find I in Profan only LOG(A) Base is 10 or LN(A) Base is e (ca 2,71828)

Also; If here someone a idea has How I these Formel in Profan present can would the a real Help.
thanks in the ahead

Umbasieren of Logarithmen goes so:

The allgmeine Logarithmus of x to Base n = Lg(x)/Lg(n) = Ln(x)/Ln(n)

The Formel would means log(x, n) = log(x)/log(n), (where n naturally never 0 or small his must)
