Bracketed Function Root Finder
Enter the real function and the different number interval, use the dichotomy method to find an approximate zero point, and check the residuals and the complete iteration process.
Bracketed Function Root Finder User manual
- Fill in the parameters or select the file according to the form, and check the unit and format first.
- Enter cos(x)-x and interval 0 to 1 to obtain an approximate root of about 0.739085, and observe the interval shrinkage.
- Click the processing button to view the results, you can copy or download and save.
Calculation method and processing rules
Repeatedly narrow the sign-changing bracket while checking its half-width and the function residual. Computation is bounded and input is never executed as code.
scope of use
The function must be confirmed by itself; there may be even heavy roots in the interval of the same number, and this tool will not traverse all the roots or prove uniqueness.
Will the input content be saved on the server?
This tool handles input in the browser, and does not upload files or form content. Typing practice scores are only saved in the native browser.
Why may the result be different from other tools?
The function must be confirmed by itself; there may be even heavy roots in the interval of the same number, and this tool will not traverse all the roots or prove uniqueness. Please compare the input unit, rounding method, applicable rules and data version first.
