Jeg legger inn punktene (0 , 0.6) , (100 , 0.9) , (200 , 2.3) , (250 , 3.3) og (300 , 4.4) og ønsker å finne en andregradsfunksjon som går gjennom punktene. Jeg bruker kommandoen RegPoly[liste1,2] og får som svar
f(x)=0x^2 + 0x + 0,57. Hvordan får jeg flere desimaler i svaret ?

Hi plecoptera,
It is surprising but the result is correct! :anguished:Try the following sequence:
liste1={(0, 0.6), (100, 0.9), (200, 2.3), (250, 3.3), (300, 4.4)}
<<right mouse click>> then >Show all objects
FitPoly[liste1, 2]
And don't forget
Options>rounding>5 decimal places !!!!
… Nice, isn’t it! :D :D
Cheers, :wink:
