Romberg Integration Calculator
Compute the definite integral of a function using Romberg Integration for higher accuracy.
Notes:
Romberg integration combines the trapezoidal rule with Richardson extrapolation
to improve accuracy of definite integrals:
R(k, m) = R(k, m-1) + [R(k, m-1) - R(k-1, m-1)] / (4^(m-1) - 1)
Higher iterations give more accurate results.
Enter a function in standard notation and specify integration limits. The calculator uses numeric approximation.
