Trapezoidal Rule
Calculate integrals using the trapezoidal rule
Examples: sin(x), exp(-x^2), ln(x), sqrt(x), pi
Numerical estimate: 2.666668
Error estimate
0.00000133333333337
Intervals
1000
Method: Composite trapezoidal rule
This is a finite-sample numerical approximation, not symbolic calculus or a proof that a limit exists. Check discontinuities and the reported error estimate.
