FOURTH ORDER APPROXIMATION

Objective: Derivation of FOURTH ORDER APPROXIMATION OF SECOND DERIVATIVE We use Taylor series approach in order to arrive at fourth order approximation. The theoritical derivation is as follows: MATLAB CODE: % Main Body of the programclear allclose allclcx = pi/3;dx = linspace(pi/4, pi/4000, 20);%dx = 0.1;for…
