About this exam

This is a 2012 midterm exam paper for computational-methods at aau (electrical-computer-engineering). This is a Midterm Examination for the Computational Methods course (ECEG-2102) at the Addis Ababa University Institute of Technology, administered in April 2012. The exam evaluates students' understanding of numerical analysis techniques and their application to engineering problems. **Key Topics Covered:** Number systems, numerical error analysis (round-off vs. truncation, ill-conditioned systems), floating-point representation, bracketing and open methods for root finding (Bisection, Secant, Regula-falsi, Newton-Raphson), and linear algebraic systems (Gaussian Elimination with scaling and partial pivoting). **Exam Structure & Format:** The exam is worth 100 points with a 3-hour time limit, divided into three parts: Part I (Number Systems and Numerical Error Analysis), Part II (Bracketing/Open Methods), and Part III (Gauss Elimination).
