Q2. a) Use the ideas of Richardson's extrapolation and Romberg's method to evaluate the first derivative of f=ex at x=0.
To construct the first column of the Romberg's table, use the formula ex+h-exh and h=10-1, and proceed by halving
h. Write a code to construct the Romberg's table and provide its output. Create a table as large as necessary to calculate all 15
decimal places of the integral correctly, if possible. If not, how low does the error get with this approach? Is subtractive
cancellation still a concern? Compare the results with that of the previous question.
b) Repeat part (a) starting with the formula ex+h-ex-h2h and h=10-1.
