1. What does popt and pcov mean? Ans: The curve fit function returns two items, which we are popt and pcov. lets assume func  = ax + b 1) popt stands for optimal paramaters, The popt argument are the best-fit paramters for coefficient(a,b) of a function, the values of popt are not exact because there are only a limited…
