Inputs explained
- Function [required]
- Initial guess [required]
- Tolerance [required]
Formula / method
x_{n+1}=x_n−f(x_n)/f′(x_n) (calculator id: newton-raphson-calculator).
Worked example
Worked values: function = x^2-2, initial = 1.5, tolerance = 1e-10 → root = 1.4142135623730951, iterations = 4
Interpreting results
Cross-check with a simple numeric example before relying on extreme inputs for newton-raphson method.
Assumptions
- Newton-Raphson Method is computed only from the fields you enter on this calculator. [newton-raphson-calculator]
- The wired execution function for `newton-raphson-calculator` is the source of numerical behavior.
- Real-number arithmetic is used unless newton-raphson method explicitly needs integers.
Limitations
- Edge cases outside the intended domain of newton-raphson method may error or look unstable—treat them as out of scope.
- If multiple conventions exist for newton-raphson method, this calculator uses the convention implemented in its engine path.
- Complex/branch cuts and undefined points are not always interactively annotated for newton-raphson method.
Important note
Educational mathematics tool. Check edge cases and domain restrictions when results look unexpected.
