Hi,

I am trying to fit data to a function. I used the funtion Fit() but the results werent right. This is what i did:

 

T := Vector([600, 800, 1000, 1200, 1400, 1600, 1800, 2000, 2200, 2400], datatype = float)

 

Kpco2F := Vector([1.22179966016487*10^20, 8.12830516164100*10^13, 1.66341265037017*10^10, 5.80764417521312*10^7, 1.03276140576140*10^6, 50815.9442560561, 4931.73803954936, 765.596606911256, 168.267406107047, 47.7529273657691], datatype = float)

 

 Fitco2Exp := Fit(a*2.71828^(-b/t), T, Kpco2F, t)

 

The regression calculated was:

Fitco2Exp = 1.*2.71828^(-1./t)

 

Both a and b were calculated has being 1 wich is wrong.

 

Thanks for the help.
