Finding roots of equation
WebOct 29, 2015 · So finding roots are at least as important as solving equations. And the importance of finding solutions of an equation are determined by what the equation is being used to describe. Edit: Your description of a field extension does not explain how those roots are "produced", nor does it try to. So you should not expect to understand … WebIn mathematics and computing, a root-finding algorithm is an algorithm for finding zeros, also called "roots", of continuous functions. A zero of a function f , from the real numbers …
