... Finding and Nonlinear Sets of Equations 9.0 Introduction We now consider that most basic of tasks, solving equations numerically. While most equations are born with both a right-hand side and a ... effort, but also with understanding and increased self-esteem. Hamming’s motto, “the purpose of computing is insight, not numbers,” is particularly apt in the area of finding roots. Yo...
