Ah :smile:, I think that is what most people here were trying to say? As for my project, i don't think it really matters which function is used, as long as the right value is produced with given parameters... In addition: are all different kinds of functions included in CurveExpert?

I'm not modeling, just getting the function from a curve. The range where the function delivers good values is the range I'll use. Otherwise I need another curve ;-) First of all, it will be free. Second, I'm not modeling, scientists do. I just use their (scientifically motivated) data...

Wow, it's all very logical to read. Especially about the sum of residuals which needs to has the lowest value to get the most optimal fit. I have a very good skill of thinking conceptually and visualizing data and models, but I have very little functional knowledge of math operators etc...

Sorry my bad. I do not have a good view of how all curves will look, so i just really need a general way to get 'a function from a curve'. I'm not experienced enough to look at functions and quickly see which parameter to change, or which parameter to add/subtract to get a specific result...

Lol uart, thank you for the input, but you didn't really get the question... The curve that I attached was just an example. I need to get functions of a lot of curves... I can get them with CurveExpert...

I think this will take some time lol. I imagine that after defining some functions with the help of CurveExpert, I could guess the function i should use, and maybe approximate the coefficients. For now I think I have to stick to the program.. I included the sample graph solely for its curve...

Thank you, this is exactly what I needed :approve: This is kinda for a secret project.. but are there any nutritional experts here?

So, if I'm correct (see attachment): 1.) I fill in the numbers 2.) I do the Curve Finder 3.) I see my function Or do I need to be a little bit more experienced with math before I do these kind of things? :wink:

No, a way :-p

Hi, i'm not a mathematician at all so I'm sorry for not using correct jargon. I need to create functions that give a specified output. I'm able to draw the graphs that should correspond with the output values of the function, however I haven't got a clue how to get the corresponding...
