write a program in Octave to evaluate the second order derivative of the analytical function exp(x)*cos(x) and compare it with the 3 numerical approximations

Objective: Here the objective is to derive 4th order approximations of the second order derivative of the analytical function exp(x)*cos(x) and compare it with the 3 numerical approximations such as in forward difference scheme(FDS),backward difference scheme(BDS) and Central Difference(CDS) and with the help of plot to compare the…
