rok Zadanie 9. Production of grapes in Italy is presented in the table below: 1965 1970 1980 1985 1990 1991 produkcja x 10 kg 17769 2400125961 34336 29036 33117 Use natural third order spine function to determine the productio in years 1962, 1977 and 1992. Compare those values with exact data: 12380 27403 i 32059. Afterwards compare results obtained with Lagrange interpolation.
