Which one do you need?
- Newton-Raphson Method Calculator
- Solve f(x) = 0 by Newton-Raphson iteration. Enter f(x) and a starting guess to get the root, the full iteration table with step sizes, and the convergence order.
- Bisection Method Calculator
- Find a root by interval halving with every iteration shown: a, b, midpoint, f(c) and the guaranteed error bound, plus the iteration count the tolerance requires.
- Secant Method Calculator
- Solve f(x)=0 without a derivative. Enter your function and two starting points to get the root, a full iteration table and the observed order of convergence.
- Lagrange Interpolation Calculator
- Build the polynomial through your data points and interpolate any x. Shows every Lagrange basis polynomial, the expanded form and the divided-difference table.
