Abstract

Wu´s method is one of the most popular approach to solve multivariate nonlinear equations proposed by Wu Wentsun. Wu´s elimination method is the main idea of Wu´s method. It is widely used in mechanical proving, automated reasoning, scientific computing, computer graphics, etc. The graphics calculator is commonly used in education and advanced mathematics research. Before Wu´s elimination method has been implemented on personal computers, however it´s not adaptive for movable learning. Hence we propose a scheme and algorithm on graphing calculator according to characteristics of embedded system and implement the algorithm in Noah graphing calculator. Our program can also be used in other graphing calculator based on GIAC. It is very helpful for better understanding of elimination in multivariate nonlinear equations for mathematics education.
