Python

(a) Write a function that takes a list of function values fi and the spacing dx between them, and returns a list of values for the second derivative of the function. Test your function by giving it a list of known values for "exp(x)" and making a graph for the difference between the output of your function and the expected results. (b) Instead of using the function you have defined for part (a) use 2 times the function you have defined in Exercise 6.1 for the 1st derivative. Again test your function with "exp(x)" and plot the difference between the output of your function and the expected results.
