Note, the text uses h instead of Δ t. Example 1 Find approximate values of the solution of the given IVP at t = .1, .2, .3, .4 using Forward Euler with Δ t = .1: y ′ = 2 y − 1; y ( 0) = 1.Estimate the value of the first derivative using the forward, backward and central finite difference. Plot the approximated values from each method on the same plot once along horizontal direction x and once along vertical direction y for the kick angle of 40. Label the plot and discuss the error. code is:The adjoint and forward problems are solved by using Newtons method, whose accuracy is implemented and tested. The methods for the solution of the problem are also formulated, verified and numerically tested in Matlab. The results give rise to a discussion that verify the accuracy of Newtons method and present it as useful for future work.Forward Interpolation using MATLAB: %Newton’s Forward Difference Formula MATLAB Program x=[0 2 4 7 10 12]; % inputting values of x fx=[20 20 12 7 6 6]; % …The finite difference method (forward, backward, and central finite difference)need to be used to approximate the derivative of an equation.
