i am supposed to
generate two graphs which i did on vm.x1 and the second of vm vs.x2 and comment on the trends observed
2.develop a 3rd order polynomial fit of vm vs. x2 and use this fit to predict values of vm at the x2 values of 0.06,0.07,0.08,0.09
3.find the value of the derivative of the 3rd polynomial fit function with respect to x2 (use the values from the original x2 data).
