Numerical Methods Calculator
Use bisection, Newton-Raphson, trapezoidal and Simpson methods for numerical approximation.
Choose a numerical method and enter f(x).
Numerical root finding and integration
Bisection is robust when the function has opposite signs at the interval ends. Newton-Raphson can converge faster but depends on a useful initial guess and a non-zero derivative.
For numerical integration, increase the interval count for a finer approximation. Simpson uses an even number of intervals automatically.
