Curve Fitting) In an engineering problem, we know that there is the following quadratic relationship between X and Y Although we know the structure of the relationship, we do not know the parameters a, b and c. To find these parameters, we do 11 measurements and for different values of X, record the value of Y. The following is the result of the 11 measurements we have made (there is a little noise, so the measurement is not 100% accurate) 3 Y measured 99 6.1 3.1 1.35 0.6 08 2.1 4.1 7.5 115 16.9 We want to find the best possible values of a, b, c using the measurement above. The best values will result in the least error sum. For example: Lets assume a -1, b--1 and c-0.5. Then based on the formula if we put x = 3, then Y will be
