Hi
I have used Mathematica 4.2 to solve this problem
points = {{23400, 273.2}, {6800, 298.2}, {2400, 323.2}};
T[R_] = NonlinearFit[points, B/Log[R/Ro], {R}, {B, Ro}];
wihich gives the result as
4021.05/Log[105.49 R]
That is a good result, but when I try to do the same in Mathematica 5.0
I get error messaeges and an other solutions, which is surely bad
1556.90/Log[-0.014 R]
Why doesn't work FindFit for this function in Mathematica 5.0
