Numerical Methods For Engineers Coursera Answers May 2026

Many past learners share their MATLAB/Python code (not just final answers) on GitHub. Search for:

Example use: Compare your Newton-Raphson loop structure to a peer’s on GitHub. See if you forgot to update the derivative at each iteration. numerical methods for engineers coursera answers

Instead of a generic answer, here’s what a typical correct response looks like for a common coding problem: Many past learners share their MATLAB/Python code (not

Prompt: Write a MATLAB function [root, iter] = newton_raphson(f, df, x0, tol) that returns the root of f given its derivative df, starting at x0, with tolerance tol. Example use: Compare your Newton-Raphson loop structure to

Correct function structure:

function [root, iter] = newton_raphson(f, df, x0, tol)
    iter = 0;
    x = x0;
    while abs(f(x)) > tol
        x = x - f(x)/df(x);
        iter = iter + 1;
        if iter > 1000
            error('Did not converge');
        end
    end
    root = x;
end

Expected test output for f(x)=x^3-2, df=3*x^2, x0=1, tol=1e-6: root ≈ 1.259921, iter = 6

Prof. Chasnov has published free companion eBooks (on GitHub and his website) that contain many worked-out examples. While not identical to quiz questions, they mirror the exact methods.
