Lecture
This lecture focuses on the convergence of Newton's method, a fixed-point iteration technique used for finding roots of functions. The instructor begins by discussing the importance of understanding the method's convergence properties, particularly in relation to the derivative of the function at the fixed point. The lecture includes practical examples, where students are tasked with studying various functions to determine their fixed points and analyze the nature of these points (attractive or repulsive). The instructor emphasizes the significance of graphical representations in understanding the behavior of sequences generated by the method. Additionally, the lecture introduces the use of Python libraries such as NumPy and SciPy for implementing these numerical methods, allowing for efficient computation of roots. The instructor also provides insights into the upcoming control exam, highlighting key topics and methods that will be assessed. Overall, the lecture combines theoretical concepts with practical applications, reinforcing the students' understanding of numerical analysis and its relevance in computational mathematics.
