Curve Fitting an equation

Is it possible to curve fit Eqn 16) using the polyfit()/ polyval() function? If not, what is an easier way of doing so?

In my code, the values of "EI" and "L" are different, so that would cause a change in the fitted value, ie, Eqn 17).

You can try using a rational polynomial fit in this exercise if the variable x is also present in the denominator.

[Arjun Siddharth]

you mean just take the ratio and compute the value?
