Trapezoidal rule for definite integrals: Enter a function f(x), use the a and b sliders to choose the limits of integration, and use the n slider to increase the number of subintervals.
Errors in the Trapezoidal Rule and Simpson's Rule: Formula and simple, step by step example with solution. Calculating error bounds.
The usual procedure is to calculate say $T_2$, $T_4$, $T_8$, and so on until successive answers change by less than one's error tolerance. This is theoretically not good enough, but works well in practice, particularly if you cross your fingers.
