Comparisons of five numerical methods for finding the roots of nonlinear functions / Atiqah Johari
Most problems in engineering and science field can be in the form of root finding. In addition, the solution of finding the root of function can be solved either in analytical methods and numerical methods. However, these analytical methods are quite complicated and difficult. Researcher tends to us...
