Rootfinding for Nonlinear Equations

> 3. Rootfinding Rootfinding for Nonlinear Equations 3. Rootfinding Math 1070. > 3. Rootfinding Calculating the roots of an equation f (x) = 0 ( ). is a common problem in applied mathematics. We will explore some simple numerical methods for solving this equation, and also will consider some possible difficulties 3. Rootfinding Math 1070. > 3. Rootfinding The function f (x) of the equation ( ). will usually have at least one continuous derivative, and often we will have some estimate of the root that is being sought. By using this information, most numerical methods for ( ) compute a sequence of increasingly accurate estimates of the root. These methods are called iteration methods. We will study three different methods 1 the bisection method 2 Newton's method 3 secant method and give a general theory for one-point iteration methods. 3. Rootfinding Math 1070. > 3. Rootfinding > The bisection method In this chapter we assume that f : R R , f (x) is a function that is real valued and that x is a real variable.
