1. Fit these six (x,y)-values with a straight line：
x 1.2 3.1 5.6 6.2 8.8 9.1
Y 4.957 12.909 23.404 25.981 36.907 38.212
a. Do this assuming that the x-values are free of errors, given y = f(x)
2. These data are measured solubilities of n-butane in liquid anhydrous
hydrofluoric acid. Fit to the equation S=a*exp(b*T) using least squares.
(This is important in a process that converts n-butane to i-butane, which
gives a higher octane number to gasoline.)
T, ℉ 77 100 185 239 285
S,wt. ％ 2.4 3.4 7.0 11.1 19.6
請數值分析高手幫個忙.....謝謝
