Numerical Methods in Engineering with Python, 2nd Edition is a text for engineering students and a reference for practicing engineers, especially those who want to explore Python. Brent method in finding the root is replaced with Ridder methods, and methods of Fletcher-Reeves optimization dropped support decreased simplex method. Examples which follow individual topics fall into two categories: hand calculations that describe the inner workings and methods of small programs that show how computer code that is used in solving problems.
