Curve Fitting

Objective: 1. \'popt\' and \'pcov\' are arrays into which the outputs of the function \'curve_fit\' are stored. popt is the array that has the optimum co-efficients off the cubic equation. And pcov is a two-dimensional array that contains the estimated covariance of the parameter in \'popt\'. 2. \'np.array()\' is used to create numpy…
