| Your Symptom | The Actual Mistake | The Numerical Answer | | :--- | :--- | :--- | | "Bisection method doesn’t stop" | You forgot to update f(a) or f(b) inside the loop. | Re-evaluate fa = f(a) after each interval change. | | "Newton’s method gives NaN" | Derivative is zero. | Add a condition: if abs(df) < 1e-12: break | | "LU decomposition error" | You overwrote the diagonal of A. | Store the multipliers in a separate lower triangular matrix. | | "RK4 for pendulum is unstable" | Timestep too large for angular velocity. | Reduce h or use an adaptive step method (not taught, but the answer to "why?") | | "Curve fit looks perfect but homework fails" | You used polynomial degree = number of points -1 (overfitting). | Use a lower-degree polynomial or spline. |
