program for bisection method in fortran language

(sin(x), cos(x), x^2)Ģ) The beginning point over which the function or expression is to be evaluated (a number).ģ) The end point over which the function or expression is to be evaluated (a number).Ĥ) The step size. The function or expression can also be changed in order to evaluated different functions or expressions.įor the algorithm to work, 5 parameters must be entered.ġ) A function or expression to be evaluated in terms of x. A word of caution: There is a limit to how small the step size can be before the the program starts to bog down, and the smaller the step size the longer it takes to find all the roots. All the parameters can be changed in order to view the function over different intervals or over different step sizes. Once the code has been executed, the bisection algorithm can then find the root(s) of the function or expression. If you have any questions, comments, or suggestions on how to make this worksheet better please e-mail me. With some work, it would be possible to extend this algorithm to finding roots of functions that do not meet the bisection criteria. As it stands, this algorithm finds the roots of functions that bisect the y-axis. This was a short project written for a Numerical Analysis class.
